This has been fixed in 3.01 that is supposed to come out today or tomorrow...
as a quickfix, open template ADV_GALLERY_BROWSEIMAGES
find class="thead" (its there 4 times) and change to class="theadx"
(just add an x to thead)
But you will have to revert the template after installing 3.01
Actually you could also remove the class="thead" as it has become obsolete and that vbulletin has added a .thead class to its own css causing the break of layout.
