We’re getting never-ending problems at the moment with the dreaded “The preview was unresponsive after loading. This is most often related to a plugin conflict or aggressive page cacheing.” message when loading Cornerstone.
We run a WP Multisite instance from Cloudways and current use their Breeze cache plugin and varnish enabled on the server with exceptions added in both for the “/x/” path in an effort to fix the issue.
Please help in getting to the bottom of this as we’re now effectively unable to update content across all our client sites. I have seen a number of other threads and troubleshooting reference for this error however none of this seems to have helped thus far.
