When we 'edit' with cornerstone we get an Error 500

[aminternetdesign]

Hi,

On one of our sites whenever we try and use cornerstone it now hits an error 500 page.

It worked fine in the past and deactivating plugins hasn’t made any difference.

I’ve tried copying the site locally and it works without problem, can you advise anything else to check?

Thanks in advance,
Mark

Hello Mark,

Please follow up the steps below:

1. Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.

2. Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see if the problem remains. If it’s fixed, you’ll know a plugin caused the problem, and you can narrow down which one by reactivating them one at a time.

3. Make sure that you’re running at least PHP v5.6.x or later to avoid any WordPress related incompatibility issues. If you’re not sure what your server configurations and settings are, install a plugin like WP-Serverinfo (https://wordpress.org/plugins/wp-serverinfo/) and check your server info by head over to Dashboard -> WP Serverinfo area.

4. Check your PHP Max Execution Time and set it for 120 for optimal usage (https://thimpress.com/knowledge-base/how-to-increase-maximum-execution-time-for-wordpress-site/).

5. Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.

If you still have problems kindly get back to us with the result of the steps above and URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.

Thank you.

Hi Mark,

You can login through FTP then edit the wp-config.php file and find the line: define( 'WP_DEBUG', false );. Set it to true then save the file. Log back in the admin area and you should be able to see some more error information when you redo the steps you are having issues with.

If you are getting an error message that suggests: Fatal error: Allowed memory size of xxxxx bytes exhausted, it means that you need to have the PHP memory limit of your site increased.

To do this, please edit your wp-config.php file and insert these lines:

    define( 'WP_MEMORY_LIMIT', '256M' );
    define( 'WP_MAX_MEMORY_LIMIT', '512M' );

You can add it before the line
/*That's all, stop editing! Happy Blogging. */

In case the issue persists, please try to get in touch with your hosting provider and confirm to them that your PHP memory limit is increased.

Ff you are still having an issue, please provide us with the FTP details of your site in a Secure Note so that we can check this further.
