HTTP ERROR 500 on nav-menus.php

#1

Hello,
Since updating to the current X theme, when I go to edit the menu under “Appearances” I get the following error:
This page isn’t working
homefiresprinkler.org is currently unable to handle this request.
HTTP ERROR 500

Any thoughts?
Thanks.

Hi there,

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.

In case you are not sure how to proceed with the error info, kindly post it here so that can provide some suggestions.

Hello @mclukens,

Thanks for updating the thread.

Ideally you should see define('WP_DEBUG', false); at around line number 83. Here’s screenshot

In case that line as deleted then you can add it back by adding the above siven code.

Thanks.

Hi @mclukens,

The notice is just a PHP notice. It will not affect any feature or issues in your site. It is displaying because debug mode is enabled. As soon as you disable the debug mode, the notice will no longer display. The notice usually informs that a certain variable is undefined, not yet set or null.

By the way, the error in the nav menus could be because of PHP time out or PHP memory limit exhaustion. One thing I know is that having several menu items will have problems in the menu management especially if you are timed out or the memory limit has been exhausted. Please provide us ftp login details so that we can investigate further.

Thanks.

Hey There,

For the theme to work properly, it needs to run Cornerstone plugin even if you are not using it as a page builder. ​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.
