This is what I did.
I FTPed the data files into the data directory and made sure all permissions were set correctly on all folders listed on the install directions. (I had already ftp the photopost files before hand.) The original database was already there and I kept the original prefix pp_ . I ran the install of 6.02 and filled in all the information I thought I was supposed to for the integration of the forums. Then I ran an upgrade from version 5.01 through to the end.
Where did I miss something?
