Re: "Forward page not found"
You might have a FORWARDING Page set-up, which doesn't exist (no page selected in your JumpTo). This is a TL Setting, as the catalog doesn't use this error message. It could also be another extension like FolderURL, which is incompatible with the catalog extension.
Re: "Forward page not found"
thanks for your quick help. seems that it is not enough to deactivate the folder-url settings in the global settings menu. i just deactivated the whole folder-url extension and everything works fine again.
