Woke up this morning to find all category tags disassociated from my Blog posts. They are showing in the dashboard summary category count ('9 categories') but clicking into the category section shows no categories and when I add a new category it shows briefly but does not save (although the Category count increases so it's going somewhere).
If I try and add a category that I previously had, it tells me I can't as this category already exists. The categories are obviously in there but are NOT showing or associating with current posts.
I have updated to 3.0.5 but this has not helped in any way.
Any ideas or tips? I had a play around with phpMyAdmin but I really am not sure what I'm doing in there.
Any tips???? Thanks folks!
