You should be posting this over on vb.com. Actually, first you should search over there because I've seen this posted before. And, I'll further add that you should read the announcement prior to installing. It very clearly says to disable your plugins which you have not done.

Can we run Beta 3 in production?

The official answer is that you may run this beta release on public sites, but we don't recommend it. If you put it in production, make sure to back up all of your data and files before upgrading.

Please remember that there is no official support for vB4 until the Gold release, so if you decide to put it in production, you're taking all of the usual risks of using beta-stage software. This means that there are still known bugs, some of which might be significant to your members, depending on how they use the software.

Is there anything we should be especially careful of?

New, fresh installations have been relatively predictable, but we have experienced some potentially serious issues upgrading existing vBulletin installations, depending on customization, configuration and certain aspects your database. In particular, disable all of your plugins before attempting upgrades.
