Nope,,,
None of the offered solutions worked for me. Funny enough,,, I installed a brand new blog,,, went pretty good altogether,, then I went and had a smoke and a coffee,,, and when I came back,, I refreshed the page and OOOOPSSS,,, all gone,,, POOOFFF! Unless a squirrel sneaked up and changed something, I must have a computer ghost!
WordPress,, shame on you to claim the release to be stable. The more I am studying this thing,,, the more I am disappointed with a bad job.
