Cornerstone Issue:

[bycor]

I’ve recently updated Cornerstone to its latest version and when trying to load the visual editor, the following error appears:

“The preview could not load due to the iframe response being incomplete. This is most often related to a plugin conflict, or customizations introducing a PHP error.”

I’ve tried deactivating other (non-X related) plugins to see if the issue was stemming from a conflict among plugins, but haven’t had any luck resolving the issue.

Thank you!

Hey @bycor,

Thanks for testing for plugin conflict. That is just one of the factors that could cause that error though. Please do try the other possible solutions below before we investigate.

1. Theme Update
2. Increasing Php Memory Limit
3. Disabling Cache
4. Disabling Cdn
5. Version Compatibility

Only if none of that helps, please give us the following information in a Secure Note.

• WordPress Login URL
• Admin username and password

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

Thanks.

Thank you! I’ve updated my note above with the secure note information.

Hi @bycor,

Thanks for reaching out.
It seems that the X (version 7.1.2) theme has not been updated to the latest version but the Cornerstone (version 5.1.5) has been updated to the latest version. The issue you are having might be due to the incompatibility between X and Cornerstone. I would also suggest you follow the below steps while updating the X theme and the Cornerstone.

1. Delete the Cornerstone existing one
2. Update the X theme to the latest version on automatic updates
3. After deletion of the Cornerstone, please use the link in the dashboard to automatically install the Cornerstone.

Hope it helps.
Thanks

Thank you @tristup! That did the trick – I appreciate your helpful steps. I hadn’t realized the version haven’t been auto-updating, and I was looking in the wrong place.

I do have a separate question, which is in regard to updating pages with Cornerstone and not seeing the changes take effect on the live site just yet. I check in an incognito tab and separate device as well in case my browser is caching the older version of the page. The updates do register, but not always right away. Do you have insight into what the delay might be from?

Thanks again for your help – I really appreciate it!

Hi @bycor,

Great that it works for you. You may need to clear the cache through the X > Settings > System > Clear Style Cache.

Hope that helps.
Thanks
