Why Your Elementor ConvertKit Integration Might Not Be Working

Before we jump into the solutions, understanding the potential root causes of why your Elementor ConvertKit connection isn’t working can help you diagnose the issue more effectively. These often stem from misconfigurations, compatibility glitches, or external factors.

Common Causes for Elementor ConvertKit Issues

• Incorrect API Key/Secret: This is by far the most frequent culprit. A misplaced character, an old key, or using the wrong key can break the connection.
• Form Field Mismatch: Elementor form fields might not be correctly mapped to ConvertKit custom fields or standard fields.
• Plugin Conflicts: Other WordPress plugins can sometimes interfere with Elementor’s functionality or its integration modules.
• Caching Issues: Server-side or WordPress caching can prevent new configurations from taking effect.
• Theme Conflicts: Less common, but certain themes can interfere with plugin functionalities.
• Elementor or ConvertKit Plugin Not Updated: Outdated software can lead to compatibility issues and security vulnerabilities.
• Server-Side Restrictions: Your web host might have certain security settings or resource limitations that prevent proper API communication.
• Network Issues (Rare): Temporary network issues between your server and ConvertKit’s servers, though this is usually transient.

Solution 1: Verify Your ConvertKit API Key and Secret

This is the first and most critical step when your Elementor ConvertKit integration is not working. An incorrect API key or secret will prevent any communication between your WordPress site and ConvertKit.

Step-by-Step API Key Verification

1. Log in to your ConvertKit Account: Go to app.convertkit.com and sign in.
2. Navigate to Account Settings:
   • Click on your profile picture or initials in the top right corner.
   • Select Settings from the dropdown menu.
3. Find the API Section:
   • On the left sidebar, click on Advanced.
   • You’ll see your API Key and API Secret listed there.

   Important: If the API Secret is hidden, you might need to click “Show” or generate a new one if you don’t have it saved.

4. Copy Both Keys: Carefully copy both the API Key and API Secret. Ensure there are no leading or trailing spaces.
5. Go to Your WordPress Dashboard: Log in to your WordPress admin area.
6. Access Elementor Integrations:
   • Navigate to Elementor > Settings.
   • Click on the Integrations tab.
   • Scroll down to the ConvertKit section.
7. Paste and Save:
   • Paste your ConvertKit API Key into the ‘API Key’ field.
   • Paste your ConvertKit API Secret into the ‘API Secret’ field.
   • Click the Save Changes button at the bottom of the page.
8. Test Your Form: After saving, go to your Elementor page with the ConvertKit form and submit a test entry. Check your ConvertKit account for the new subscriber.

Tip: If you’ve recently rotated your API keys in ConvertKit, make sure you’re using the latest ones in Elementor.

Solution 2: Check Elementor Form Field Mapping with ConvertKit

Even with correct API keys, if your Elementor form fields aren’t correctly mapped to the corresponding fields in ConvertKit, the data won’t transfer. This is a common hiccup when your Elementor ConvertKit integration is not working.

Step-by-Step Field Mapping Configuration

1. Edit Your Elementor Page/Template: Open the page or template containing your form with Elementor.
2. Select Your Form Widget: Click on your Elementor form widget to open its settings in the left panel.
3. Go to Actions After Submit:
   • Under the ‘Content’ tab, expand the Actions After Submit section.
   • Ensure ‘ConvertKit’ is added as an action. If not, type “ConvertKit” and select it.
4. Configure ConvertKit Settings:
   • A new section named ConvertKit will appear below ‘Actions After Submit’. Expand it.
   • API Key: Select ‘Default’ if you’ve set it globally in Elementor Integrations, or ‘Custom’ to paste it directly here (though global is recommended).
   • List: Select the ConvertKit Form that you want to connect your Elementor form to. This is crucial as it determines where subscribers land.
5. Map Form Fields:
   • Expand the Field Mapping section within the ConvertKit settings.
   • For each field in your Elementor form (e.g., Name, Email), ensure it’s mapped to the correct ConvertKit field.
   • Email: Must be mapped to ‘Email’.
   • Name: Should be mapped to ‘First Name’ or a custom ‘Name’ field if you have one.
   • For any custom fields you use in Elementor (e.g., ‘Company’, ‘Phone’), make sure identical custom fields exist in ConvertKit and are mapped correctly here. Navigate to your ConvertKit account > Settings > Advanced > Custom Fields to create new ones if needed.
6. Update and Test:
   • After thoroughly checking all mappings, click the Update button at the bottom of the Elementor editor.
   • Test your form live on the page and verify that all data appears correctly in your ConvertKit subscriber list.

Tip: If you’re having trouble with a specific custom field, try simplifying your form first with just Name and Email to ensure the basic connection works, then re-introduce custom fields one by one.

Solution 3: Clear Caching (WordPress, CDN, Browser)

Caching can be a powerful tool for website speed, but it’s also a notorious culprit when configurations don’t seem to take effect. If your Elementor ConvertKit integration is not working after making changes, caching is a prime suspect.

Step-by-Step Cache Clearing

1. Clear WordPress Caching Plugin:
   • If you use a plugin like WP Super Cache, W3 Total Cache, LiteSpeed Cache, or WP Rocket, go to its settings page in your WordPress dashboard.
   • Look for an option like “Clear All Cache,” “Delete Cache,” or “Purge All Caches” and execute it.

   For example, with WP Rocket, you’d navigate to WP Rocket > Dashboard and click Clear Cache.

2. Clear Server-Side Cache (if applicable):
   • Many hosting providers (like Hostinger, SiteGround, WP Engine) offer server-level caching.
   • Log in to your hosting control panel (e.g., hPanel, cPanel, my.wpengine.com).
   • Look for cache management options (e.g., “Performance,” “Caching,” “Purge Cache”).
   • Clear any active server cache.
3. Clear CDN Cache (if applicable):
   • If you use a Content Delivery Network (CDN) like Cloudflare, log in to your CDN control panel.
   • Find the caching section and purge the cache for your domain. In Cloudflare, this is usually under Caching > Configuration > Purge Everything.
4. Clear Browser Cache:
   • Even after clearing server and WordPress caches, your browser might still be serving an old version of the page.
   • Perform a “hard refresh” (Ctrl+F5 on Windows, Cmd+Shift+R on Mac).
   • Alternatively, clear your browser’s cache and cookies.
5. Test Again: After clearing all layers of cache, re-test your Elementor ConvertKit form.

Best Practice: Always clear your caches after making any significant changes to integrations, plugin settings, or code on your WordPress site.

Solution 4: Update All Software (Elementor, ConvertKit Plugin, WordPress)

Outdated software is a common source of bugs, security vulnerabilities, and integration issues. If your Elementor ConvertKit form is not working, ensuring everything is up to date is a quick win.

Step-by-Step Update Process

1. Backup Your Website: Before any major updates, always create a full backup of your WordPress site (files and database). This is a crucial safety net if something goes wrong. Hostinger users can easily do this via hPanel.
2. Update WordPress Core:
   • Go to Dashboard > Updates in your WordPress admin.
   • If a new version of WordPress is available, follow the prompts to update.
3. Update Elementor and Elementor Pro:
   • Still in Dashboard > Updates, check for updates for Elementor and Elementor Pro.
   • Select them and click “Update Plugins.”
4. Update ConvertKit Plugin (if used):
   • If you’re using the official ConvertKit WordPress plugin alongside Elementor (e.g., for general ConvertKit functionality rather than just Elementor form submissions), ensure it’s updated.
   • You’ll find this under Dashboard > Updates as well.
5. Update Other Plugins/Theme: While you’re at it, update all other plugins and your active theme. Compatibility issues often arise from an outdated plugin clashing with a newly updated one.
6. Clear Cache and Test: After all updates, clear all caches (as detailed in Solution 3) and thoroughly test your Elementor ConvertKit form again.

Reference: For more on maintaining your WordPress site, consult the official WordPress Documentation on Upgrades.

Solution 5: Check for Plugin and Theme Conflicts

Sometimes, another plugin or your theme might be inadvertently interfering with Elementor or its ConvertKit integration. Diagnosing this requires a systematic approach.

Step-by-Step Conflict Isolation

1. Backup Your Website: Again, always back up before deactivating plugins or switching themes.
2. Switch to a Default WordPress Theme:
   • Go to Appearance > Themes.
   • Activate a default WordPress theme like “Twenty Twenty-Four” or “Twenty Twenty-Three”. This will temporarily change your site’s appearance but helps rule out theme-related issues.
   • Test your Elementor ConvertKit form. If it works, the issue is likely with your theme. Contact your theme developer for support.
   • Reactivate your original theme after testing.
3. Deactivate Plugins One by One:

   This is the most common way to find a plugin conflict:

   • Go to Plugins > Installed Plugins.
   • Deactivate all plugins EXCEPT Elementor and Elementor Pro. If you use the ConvertKit WordPress plugin, keep that active too.
   • Test your Elementor ConvertKit form.
   • If the form now works, reactivate your other plugins one by one, testing the ConvertKit form after each activation, until you find the plugin that breaks the integration.
   • Once identified, consider finding an alternative plugin, contacting the plugin developer for support, or reaching out to Elementor support.
4. Clear Cache and Test: After each change (theme switch, plugin deactivation/activation), remember to clear caches and re-test.

Tip: If you have a staging environment for your website, perform these conflict checks there first to avoid impacting your live site.

Common Issues and Troubleshooting When Elementor ConvertKit Integration Not Working

Beyond the core solutions, here are some specific scenarios and troubleshooting steps:

1. “Couldn’t Connect” or “Invalid API Key” Error in Elementor

• Resolution: This almost always points to an issue with Solution 1: Verify Your ConvertKit API Key and Secret. Double-check for typos, extra spaces, or using the wrong key type (e.g., using a form API key instead of the account API key).
• Check ConvertKit Status Page: Very rarely, ConvertKit itself might be experiencing an outage. Check status.convertkit.com.

2. Form Submits but No Data in ConvertKit

• Resolution: This usually means the API connection is successful, but the data isn’t being parsed or mapped correctly. Revisit Solution 2: Check Elementor Form Field Mapping. Ensure each field has a corresponding ConvertKit field and the mapping is exact.
• Mandatory Fields: Does your ConvertKit form require a specific field (like ‘First Name’) that isn’t marked as required or mapped in Elementor?

3. Only “Email” Field Submits, Others Don’t

• Resolution: This is a classic field mapping error. Go back to Solution 2 and meticulously check the mapping for each field beyond ‘Email’. Remember, custom fields in Elementor need exactly matching custom fields in ConvertKit.

4. Form Submits Fine in Editor, Fails on Live Site

• Resolution: This is a strong indicator of caching. The Elementor editor might be bypassing server-side or plugin caches. Refer to Solution 3: Clear Caching. Also, check for JavaScript errors in your browser console on the live page (right-click > Inspect > Console tab).

5. Form Submissions intermittently fail

• Resolution: This could point to host-related issues (temporary resource limits, firewall rules), or a subtle plugin conflict. Check your website’s PHP error logs (usually accessible via your hosting control panel). Look for any errors related to Elementor, ConvertKit, or API calls around the time of the failed submissions.
• Contact Hostinger Support: If you suspect server-side issues, your hosting provider (like Hostinger) can often provide insights from their server logs.

6. Not Seeing Specific ConvertKit Forms, Tags, or Sequences in Elementor
