My Cred form no longer works unless I disable JS composer page builder for the page. The form works fine if added directly within the standard WP editor but not when added as JS Composer element.

Link to a page where the issue can be seen: hidden link

I expected to see: The form and other content within the page and the sites standard footer.

Instead, I got: A partially built page, apparently stopping after attempting to render the Cred form.

Hi, I'd like to see if your site is registering any PHP errors. Problems that result in an incomplete page are often captured in the logs, so it could give us some insight. If you're not aware of your server logs, I can show you how to activate them:
Go in your wp-config.php file and look for define(‘WP_DEBUG’, false);. Change it to:

define('WP_DEBUG', true);

Then add these lines, just before it says 'stop editing here':

ini_set('log_errors',TRUE);
ini_set('error_reporting', E_ALL);
ini_set('error_log', dirname(__FILE__) . '/error_log.txt');

Attempt to reload the broken page at least once. If any server-side errors are thrown, this will create an error_log.txt file in your site's root directory. Please send me its contents. Once that is done, revert the updates you made to wp-config.php. If no file is generated, then we may need to follow some other troubleshooting steps.

Hi Christian,

Thanks for your help with this. I've done what you say and it's looking like some files maybe corrupt or missing. Below is the error_log.txt content.
