Yup, I got the same problem. Deleted all my old files, uploaded new. It did ask to update the data base. But when you go in, it’s all the same. Still says it’s 2.5, and I should upgrade!
Actually weird stuff is going on, buttons are fading and flashing, uploader does not work, which I know was suppose to be fixed in 2.5.1.
Guess we need a 2.5.2
