Looks like there's seriously something wrong, perhaps files from different versions of vb or remenant mods. You should either reinstalll all original vb files, and restore your last working backup

Make sure you have uploaded and overwritten the old vBulletin files. Also make sure you run the whole upgrade process from start to finish.
