Cornerstone previw after updating wordpress

The preview was unresponsive after loading:

The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.

There is no caching plugin, we changed memory limits in wp-config.php, renamed .htaccess and tried to change permalinks settings, nothing worked.
Even “downgraded” wordpress to an older version, but to no avail.
Working on a “development” server that has no real workload.

Can you help with this issue as we are hours away from going production with the site.

Thank you!

Hey @mopet38,

Do you have third party plugins and tried testing for plugin conflict? If so, please give us access to your WordPress admin in a Secure Note. If you can give FTP access that would be great.


There’s a plugin conflict with Easy Facebook Likebox. I deactivated it and Cornerstone worked fine again. Please contact the plugin developer for a resolution.


Christian you are the Best. Thank you.

You are most welcome!
