Some pages showing an error on Cornerstone

[ginadhaliwal]

Hi,

Some of my pages are showing an error when I try to open them now.
It has random HTML on the top and bottom. When I try to edit it it says that the preview could not load due to the iframe response being incomplete. It says it is most often related to a plugin conflict or a customization including a PHP error.
I do not know what to do and need to get this fixed ASAP.

Thanks!

Hello @ginadhaliwal,

Thanks for writing in! I have checked the URL associated in your license and it seems that you are using an outdated Cornerstone plugin (6.0.7) and the X theme (6.2.5). Could you please update to the latest versions?
Our latest versions are:

• X theme 9.0.8
• Cornerstone 6.0.8
• WordPress 5.8
• PHP 7.4

This latest release contains fixes for several issues so be sure to check out the changelog:

• https://theme.co/docs/changelog/x-9
• https://theme.co/docs/changelog/cornerstone-6

After doing the updates, always remember to clear all caches (if you are using WP Rocket, WP SuperCache or W3 Total Cache) when updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.
