After I have upgraded one of my sites from 6.4.3 to 6.5, adding or editing a page or post will result in a blank page. I reverted back to 6.4.3, but this didn’t help. I enabled debug mode, but nothing showed up in the error logs either.
I do see this in the javascript console of my browser:
Uncaught TypeError: wp.editPost is undefined
I have tried disabling all plugins and selecting the default theme, but this doesn’t solve the issue.
Switching to the classic-editor helps and this allows me to edit. However, I’m now missing out on the block editor. Any ideas what could be the source of this issue?
