Logged into my site today http://www.covertmag.com to find out that every post entered to date has lost its category and tag associations - all now reverted to "Uncategorized" with no Tags.
When I go to the Categories section in Posts>Categories in the back end my list of categories has disappeared, and when I try to enter a former category into the list it tells me that "the category already exists" but there are no categories here?
Is this a database problem? Andy why would this happen?
Many thanks if anybody has any ideas.
