I just wanted to make my experience public. I opted for vbulletin after trying the trial version but have been unable to install the vbulletin 5 software. My hosts support team were not able to make it work either and then vbulletin support were also unable. Amazingly they said in their email that they had seen this problem before! I got the impression that it was quite common. Yet they will not issue a refund! Potential users should be aware that this situation can occur. Although there will be no problem with the trial version, it is a roll of the dice whether your paid for full version will work at all. This wouldn’t be a problem of vbulletin took responsibility for it, but they dont. They will not refund once you have downloaded, even if, as in my case, their own support staff cant get it to work. Having asked around since then, it seems clear that as the better developers moved to xenforo it wasnt just the coding that went downhill at vbulletin. If the companies problems are so deep that they will grab small cash in this way, rather than just giving a quick refund then it does not bode well for the future. With a deteriorating platform, support staff unable to install the software and management that pay no heed to crm or protecting the integrity of their brand reputation, users would be well advised to steer clear!
