vB 4.0.2 changed the floats on a large number of objects. This report in particular was expanded to correct all style issues involving 4.0.2.
Beginning with VW 3 Beta 5, it's likely that users who stick with 4.0.1 will see style issues because so much changed in 4.0.2. Please note that we only fully support installations with the most recent build of vBulletin, the exceptions being if you have database or fatal errors when trying to use VaultWiki in earlier versions.
We are trying to get the next build out as soon as we can to address the style changes, hopefully by the end of this week.
