Hi, I am doing a upgrade for a site running on 3.31. The upgrade works fine and I checked the site for all released versions untill "4.40 Release". No problems and everything runs like it should. But then when I try the last upgrade and go to 4.5 Release, I get the error attached below. On both pages and the treemenu (in edit mode). I also get this error if I copy the (upgraded) database to a fresh (and working) 4.5 install, so I guess it has something to do with my database. Anyone seen this before?
