I’ve been experiencing a strange error in the last few days.
I can edit old articles/pages without any problem with Cornerstone’s live preview, but when I try to create a new one or even clone an older article, I get the “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.” error.
Checking the developer console, I get this error:
I already did the suggested troubleshooting that I found on other topics, but nothing seems to change.
This happened after the most recent X Theme / Cornerstone update, and seems to only affect articles created after that.
Any help would be awesome!
