For some reason Wordpress won't load page editor correctly. It loads it blank only for this one particular page (other pages load correctly). I was editing it and clicked to toggle tablet view for further styling. Editor crashed and I can't load it since then. Page works correctly at front, only editor fails to load. Console gives me this error: Uncaught SyntaxError: Unexpected token '<' (at post.php?post=7&action=edit:453:1) I've tried to: duplicate this page migrate entire site to different hosting purge cache switch themes use different browsers (incognito and not) turn various plugins on and off None of above worked. Any idea how can I fix it?
