Cornerstone 4.1 - Tab > Edit Content Issue (Blank Sidebar)

When I try to edit the content of a tab I setup I’m now getting a blank white screen within the Cornerstone editor sidebar. The content is still there but I’m unable to directly access the code I put within the “Content” area of the “Inspector” section of this “Tab”. This tab (Tab #1) is a few layers deep, here’s my setup:

Section > Row > Column > Tabs > Tab #1

I’m using Cornerstone 4.1 w/ X Theme 7.1.2, WordPress 5.3.2, and PHP version: 5.6.32

Hi @Danlaw_1984,

Thank you for writing in, please do the following:

  • Please clear all the site caches (plugin, server-side, CDN, and browser’s cache) so that the code from the latest release is always in use. This will help you to avoid any potential errors. Please deactivate this caching features while we tackle this issue.

  • Test for a plugin conflict. You can do this by deactivating all third party plugins, and seeing 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.

  • Contact your hosting provider to increase your allocated memory limit or do it yourself by adding this code in your wp-config.php file.

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

You can add it before the line:

```
/* That’s all, stop editing! Happy blogging. */
```

Let us know how it goes,
Cheers!

Thank you, I’ve found functionality was restored once I deactivated a cache plugin called WP Rocket. For some reason their plugin conflicts with Cornerstone editing.

Hello @Danlaw_1984,

Please deactivate any caching and optimizing plugins. They are best to turn ON when you are done building the your site and ready to go live.

Hope this helps.
