I have made many passes thru the photopost config and int files with all of the options. I have also used the import tool in vbulletin to import the photopost users into the vbulletin database. Unfortunately, when I think I have done things as required and change path to use the vbulletin database, Photopost throws an "unrecoverable" error. I have found a few notes on the Photopost forum that may shed more light but they suggest modifying the group IDs in the Photopost forum which I'm reluctant to do unless I know exactly what I'm doing ... which I don't. I'll do a back up of the photopost db in a minute before I start again. I sure wish there was a clear step by step guide to this. It's amazing that there isn't. If we can figure this out I definitly would like to create one to spare others. There are others who are struggling with this.
