Error when trying to update X theme WordPress 6.0.2; X Theme 4.4.2; convertplug 1.2.4

I’ve been trying to update the PHP on a site running X theme, but it seems the site encounters a critical error with the X theme and with the convertplug plugin.

I first tried updating the PhP, which crashed the site (these instructions). I was able to go into the GoDaddy Managed WordPress backend and partially update the PHP to 6.0.2, which functioned with the outdated X-theme.

Convertplug is currently at version 1.2.4;
X theme is currently at 4.4.2

Here’s the error message that displayed (after the site’s PHP was successfully updated, I got this error message when I went to update the theme):

Hello Lydia,

Thanks for writing to us.

It might be an issue with the PHP version, I would suggest you please make sure your server PHP version is 7.4 or 7.4+ as per our version compatibility page. I would suggest you please contact your hosting provider to set your server PHP version as per our version compatibility page. It is also recommended by WordPress as well. Please have a look at this article.

It seems that you are using an older version of the theme as well I would recommend you please make sure your theme, plugin, and WordPress are updated as per our version compatibility page.

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

I would suggest you follow the below steps while updating to the latest version of the theme.

  1. Delete the Cornerstone
  2. Update the X theme to the latest version on automatic updates
  3. After the X theme is updated, use the link in the dashboard to automatically install the Cornerstone. It will be in the latest version.

I would also suggest you troubleshot a few common issues on this.

  1. Testing for Plugin Conflict
  2. CSS/JS Customization
  3. Version Compatibility
  4. Disabling Cache
  5. Child Theme

If none of those work, it would be best if you could copying 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
