Cornerstone stopped working after upgrade

[romanlif]

Hi,

I’ve upgraded my X Theme and Cornerstone to the latest version.
The site works just fine, but when I attempt to edit a page with Cornerstone I get an error:
“The preview was unresponsive after loading…” (screenshot attached).

I should also note that I have WP_Rocket cache plugin which I disabled (and even completely removed) - the error persisted.

Please assist.

Hi there,

Please kindly follow the steps below:

1. Ensure everything is up to date according to our version compatibility list here. Please follow the best practices when updating your theme and plugins. Click here for more information.
2. If you’re using a CDN, please clear the CDN’s cache and disable optimization services. If you use CloudFlare read this: https://xthemetips.com/using-cloudflare-rocket-loader-with-x-pro-and-x5/928/
3. Test for a plugin conflict. You can do this by deactivating all third-party plugins, and see 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.
4. Remove custom CSS and Javascript from the options or Child Theme and test the case.
5. Reset your htaccess file by renaming it to .htaccess-bak. Then in WP Admin Menu, go to Settings > Permalinks and just click the Save Changes button.
6. Increase the PHP Memory Limit of your server. Click here for more detailed information and how to increase the PHP memory limit.
7. Check this article: https://theme.co/apex/forum/t/troubleshooting-builder-preview-warnings/14404/

If you still have problems kindly get back to us with the URL/User/Pass of your WordPress dashboard using the Secure Note functionality of the post to follow up the case.

Thank you.
