Hello. After my upgrade from WSS 3.0 to SP2010 I get an error when I try to open an image within a Image library. So if i click on the thumbail I get a unexcpected error. I figured out that when I create a new view based on the 'error' view, everything works fine. But there is a difference in the URL. 'Error' view: http://xxxxxx.com/xxxx/xxxxx/_Layouts/listform.aspx?PageType=4&ListId={B3499373-E0E6-40FD-904D-B83F996769FD}?ID=1&Source=http%3A%2F%2Fportaal%2Ehaco%2Enl%2Fprojectnet%2F119117%2FFotos%2FForms%2FAllItems%2Easpx&RootFolder=%2Fprojectnet%2F119117%2FFotos 'New' view: http://xxxxxxx.com/xxxxxx/xxxxx/Fotos/Forms/DispForm.aspx?ID=1&Source=http%3A%2F%2Fportaal%2Ehaco%2Enl%2Fprojectnet%2F119117%2FFotos%2FForms%2Ftest2%2Easpx&RootFolder=%2Fprojectnet%2F119117%2FFotos Notice the listform.aspx and DispForm.Aspx. I have over 8000 subsites with this problem. Does someboy know how to fix this?
