So... I wasn't working on my blog since some days and today I've discovered very strange thing.
- Whole categories disappear from list.
- All post are "Without category" and tags.
- List of categories in admin panel is blank.
- I can't add any categories, but they are avaiable in "Recent use categories".
- When I'm trying add new category or add the same it says there is a category with such name. Ghost?
- Also I can't edit any post to add new or old "ghost" category becouse after edit everything backs to state "without category".
What the... flock?
As I said - I don't edit any files, plugins or something. I wasn't working on my blog since one week and this thing appears today.
