I completed the 5.02 upgrade and now all my old images no longer appear and I am also no longer able to logon as the admin.
The upgrade seemed to go smoothly, but all old images no longer work correctly (new images seem to be ok). For most of the images, the thumbnail is black, and the image is broken.
The site is http://bbs.clubplanet.com/photopost/
As for logging in, it says "Login Successful!" but then takes me back to the home page without logging me in.
