Trouble when updating cornerstone Plugin

I just decided to update X-Theme with the cornerstone Plugin without any success. At any time when updating to the latest version I will then not be able to access the page. I already tried to deactivate all other PlugIns, but the same happens.

Web Site works with the following version:
X-Theme: 6.4.6
Cornerstone: 5.0.10
PHP: 7.4
Permalinks: set to “Postname”

Just deactivated all additional plugins (except Cornerstone) and updated to X-Theme 9.1.4, the system confirms --> X was updated successfully. However, when I want to access the updated page I got the error message “Es gab einen kritischen Fehler auf deiner Website.” - “Critical Error on the WebPage”

I do have to restore the page again.

Any help on that issue?
Shall I update in smaller steps?

No idea.


Hello @rdbeli,

Thanks for writing to us.

It might be an issue of plugin conflict or version compatibility. Please make sure your PHP and WordPress version is updated as per our version compatibility page.

In case if you have not seen the theme update doc please have a look at it.

I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

  1. Testing For Theme Related Issue
  2. Testing For Plugin Conflict
  3. Theme Update
  4. Child Theme
  5. Css/Js Customization
  6. Increasing Php Memory Limit
  7. Disabling Cache
  8. Disabling Cdn
  9. Permalinks
  10. Version Compatibility

If none of those work, It would be best if you could copy your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details

  • WordPress Login URL
  • Admin level username and password
  • FTP Details

You can find the Secure Note button at the bottom of your posts


Thanks, changed the order in which I update everything step by step. Now all fine.
