Chuck, I know what you are saying, but my Photopost database is inside the same database as my vBulletin database. In fact, it's the only database installed in the mySQL on my site. I did a default install using the pp_ prefix of the tables. When I look at the tables in the database, I have the vBulletin tables and in the middle are all of the pp_ Potopost tables.
Are you saying that even though it is all in one database that Photopost doesn't see it that way and I still need to uncomment out those lines and put the same information there as I have for the database in vBulletin? I'll give that a try as it is something I have not tried since all of the instructions have said it wasn't necessary.
