I am currently looking for feedback on the vBulletin importer and this issue has been raised previously in our bug tracking #1991.
At the moment I am working on updating all the forum importers for the next major release of bbPress and waiting and seeking feedback from more users as this still appears broken for some and not others but as I don’t have access to vBulletin myself I cannot test this directly myself, let alone the different versions etc
I would be more than happy to take a look at this for you and make any fixes as needed.
Drop me an email to stephen@netweb.com.au and we can discuss it further.
I’m having the same issue as well. I noticed that the tracking ticket says it has been fixed, but I’ve got nothing. 🙁
I’m willing to help out however I can to help improve this functionality. I know a lot of people would love to leave vbulletin’s shotty service and rip off tendencies after what they did to us with 4 and want to do to us with 5.
If staff wants me to make a new ticket, then let me know!
Thank you guys!
