I have an odd situation, and I don't know what's causing it. I've a site in which I can't seem to add a category. When I purchased the site, they had no categories in there. Each time I a create a category in the normal category section of wp-admin, it shows up for a minute, but then disappears. something that you guys know of that can cause a categories to disappear? I've switched themes around to see if it was related to that, and it occurs on all themes. I've looked at plugins, but cannot seem to find anything unusual there.
