I have two Custom Post types both are simple, and not different to classic post. I just use them to make separation of content.
All was right until suddenly today I cannot get into editing one of the Custom Posts type using block Editor.
Editing Standard Posts, Pages and other Custom Posts works fine. It is just this one Custom Post type is failing.
Once I enter in Add New or Edit option, editor is loaded and post displayed properly and then warning pops up: “The editor has encountered an unexpected error.”
I have options to copy post text and copy error.
Copy Post Text shows wrong Post, not the one I opened and one that was displayed moment before break.
Copy Error shows this:
