I created the master admin as part of the installation. After getting the options set I began the process of importing from vBulletin 4 (same thing I did on my other forum).
I selected the option to preserve content IDs (or whatever that one is) and imported everything.
The following may sound strange but this is what happened: When I tried to log into the new forum (front end), it said that no such user existed. I went back to the control panel in the other browser tab to discover that I was logged in as one of my other admins. Crazy!
I am not sure what happened but the only thing I can think is that he was user #1 on the VB forum and the new profile I created on XF was #1 and they were merged? I don't know what I am talking about, of course, but I am trying to make sense of it.
In any event, I deleted everything an am starting over. Should I preserve those IDs on the new import or what? This will be an import of VB4 and the albums from VB4 into the XF Media Gallery.
