When you enable AJAX form submission, there are several reasons why an AJAX submission might not save a form in WordPress. Here are some common troubleshooting steps to help you identify and resolve the issue:
Enable and Check Error Logs: #
User Registration Plugin’s Internal Logging #
- Go to User Registration > Tools > Logs.
- Review the log to see detailed error information.
Learn how to view error logs in User Registration plugin.
Server-Side Error Logs #
- Examine your WordPress error logs (usually located in the wp-content/debug.log file).
- Look for any PHP errors or warnings related to the AJAX request.
- If you’re using a custom PHP function to handle the AJAX request, check for errors in that function.
Now, if you find any error messages related to this particular issue, you can contact our support team via the live chat option at https://wpuserregistration.com/.
Inspect the Network Tab in Your Browser’s Developer Tools #
- Open your browser’s developer tools (usually F12 or Ctrl+Shift+I).
- Go to the “Network” tab.
- Reload the page and save the form.
- Look for the AJAX request related to the form submission.
- Check the request’s status code:
- 200 (OK): The request was successful.
- 400 (Bad Request): There might be an issue with the form data or request parameters.
- 500 (Internal Server Error): The server encountered an error while processing the request.
- Examine the response body for any error messages or clues.
Disable Plugins and Themes #
- Temporarily deactivate all plugins and switch to a default WordPress theme to see if the issue is caused by a third-party plugin or theme.
Learn how to check plugin/theme conflict.
Try looking out for caching plugins if you have installed it. You can deactivate them first and see if the issue persists.
Using the WordFence plugin? #
WordFence, a popular WordPress security plugin, might be blocking AJAX calls to /wp-admin/admin-ajax.php for security reasons. This is often due to suspicious activity or potential threats.
Check WordFence’s Firewall Rules: #
- Access Firewall Rules: Navigate to the WordFence dashboard in your WordPress admin area and go to the “Firewall” section.
- Review Blocking Rules: Inspect the list of blocked requests. Look for any entries related to /wp-admin/admin-ajax.php.
- Temporary Disable: If you’re confident that the blocked request is legitimate, temporarily disable the specific rule or the entire firewall to see if the issue resolves. Exercise caution when doing this, as disabling the firewall can compromise your site’s security.
Update WordPress, Theme, and Plugins #
- Ensure that your WordPress installation, theme, and plugins are up to date. Outdated components can sometimes cause compatibility issues.
Test with a Different Browser #
- Try submitting the form using a different web browser to rule out browser-specific issues.
