I have suddenly found that I cannot use Cornerstone to edit pages on a customer’s website. The error message that Cornerstone displays is the following:
The preview could not load. This is most often related to a plugin conflict or aggressive page cacheing. Checking the developer console for errors could indicate what went wrong.
Origin URL: https://kayn.nl
Preview URL: https://kayn.nl/en/discography/
I do not have any plugins installed that would affect page caching, so I’m not sure what’s going on. Any help would be appreciated.
