-I cannot use custom session any more. If I try to set the custom session on, then on login I receive the successful message, however I am redirected to the front page as if I am not logged in;
-I seem to be unable to download files through modules like wfdownload and backup. Instead of being offered to select a location for the file to be saved, the file is "displayed" in the web browser (a mess of weird characters).
To my surprise, when I turn the debug on in preferences to find out what is happening, everything works fine and I get only the customary 'Notice: only variable references should be returned.....'
Can anyone explain this mystery? I would appreciate any suggestion. Thanks for your attention.
