Hey Ken,
thanks for the reply.
I followed the advice an entered the URL. Changed some of the analytics settings and checked, if the dir permissions for analytics are ok.
It saved without problems. Still the upgradesettings keep showing under notifications. I turned the debugging in the administration area to "all" with output to the page. No errors are shown when I saved the analytics settings in the URL.
Strange...any other ideas?
Cheers
Tobias
