Jafo232, vBulletin users are not logged in when visiting the WordPress page ( which I use as homepage ). I did not come across any errors when installing. The WP to vBulletin test post worked although it was posted under my username instead of the user "comments" ( which doesn't exist ). I did the user mapping. Here are my vBBridge settings.
VB User ID: 1337
VB Username: comments
VB Forum ID: 9
