Suddenly all my categories disappeared under posts > Categories.
After putting the site in safe mode I could determine it was caused by ACF.
Upon further searching I discovered that I could not put my category field group to draft or pending review, it won’t save and simply stays active.
When I delete this category group, my category list appears again..
My category group consist of an image, a true/false field and a textarea.
Any idea what might be causing this?
I have only used these fields for 1 category, but I do have lots of content in the textarea, maybe it’s too much?
I deleted the textarea from the group and that made the categories return.. so something weird is going on with the textarea.
Edit: in the instructions field I had some html-code, where I forgot to close a class tag. Removing that content fixed it.
