Poorly Written Software Causes Many Many Duplicate Content Issues VBulletin basically does the job of a forum software, but leaves issue undetected at first, that should be revealed before purchasing. Most of the issue cannot be seen by the general public, as they are hidden in the password protected user area. None of their software will validate via the W3, which to me, clearly means that the programmers are not concerned with testing their software to make sure it is written to standards and does not contain basic underlying errors. Much much worse, is that the forum produces page after page of duplicate content, because every page can be addressed in many ways. Your Google webmaster tools account will very shortly be filled with duplicate Title tags and Duplicate Descriptions and there is literally nothing you can do about it. VBulletin's response was to create a new version 5, instead of fixing the issues with version 4 first. To their credit, they do seem to be continuing to work on V4. The support team seems to be working hard to try and help, but they do not appear to be supported by the programmers, so any issue that has any type of complexity to it, will not be solved. At least that has been my experience. If VBulletin were cheap software, I would not complain to much, but it is quit expensive, so you would think it would be very well written as such. Unfortunately it is programmed more like cheap software, with obvious and seriously written flaws. I cannot recommend VBulletin, nor can I advise against it, since I cannot recommend any other software that might be better, although I would think there would be. Should you decide to purchase, be aware of the duplicate content issues, that you will face. I would run any of there forum pages through the W3 validator, so you can get a feel for the quality or lack there of, also.

Bug ridden piece of software that will … Bug ridden piece of software that will drive you nuts trying to get it to work. Never get the mobile app add-on as it simply doesn't work at all. I've wasted so much time and energy on this software, a real regret.

Was the best until 2009, but then the developers left and it's been rubbish since We are still using vBulletin 3.8 having been a vBulletin customer since 2001. It used to be the market leading software with good reason, but in 2009 the original development team left (all but one) and the replacement coding and management team has been very poor. What was needed in 2009 was a complete rewrite. However vBulletin 4 was vBulletin 3 with code 'updates', and vBulletin 5 connect is vBulletin 4 with code 'updates'. It took years before vBulletin 4 was considered a reasonable forum solution, and vBulletin 5 is truly terrible. Way too many queries and css definitions. Full of bugs just like vB4 was on release. We're migrating away from vBulletin as soon as possible, having seen that vBulletin 5 is not a viable product. In summary. vBulletin used to be the best. Now it's terrible. AVOID.

Don't use Don't use I decided to use some other forum engine as this software is very outdated, support is nonexistent and better engines exist. Looks like the company has no plans for addressing these problems. The support guys are silent on the case too.

Great! This forum software was just absolutely brilliant for my new company. It provided everything I wanted even more!
