Cannot Load Customizer Fatal Error

Support
#1

My website has X Theme installed and everything was working fine.

Now however when I click on Appearance > Customiser. I either get a Fatal Error or a Page not Found.

The Theme is updated to 5.1.1 and WordPress is updated to the latest version. No new plugins have been installed.

Please advise as this is really urgent!

I can Provide Login Details

Hi there @RonaldFernandes,

Thanks for writing in!

As everything was working fine has anything recently changed apart from the update to 5.1.1?

Has Cornerstone also been updated to 2.0.6?

Have any other plugins also been updated recently?

As you mentioned there’s a fatal error could you paste that here please for us to take a look?

Thanks!

Hi @Jack yes Cornerstone has been updated.

No recent plugin updates that were done before the error showed up that I can remember. updates to plugins were done after the error though.

Here is a screenshot of the error

if not the fatal Error then I get a Page not found.

Hello There,

Thanks for updating in! The error is because of PHP memory limit exhaustion. We recommend that you increase your memory allocated to PHP. To increase it, 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. */

We would loved to know if this has work for you. Thank you.
