Hello Dani,
i removed the Globals from the adminfolder and put it back into the Globalsfolder.
I could login now and everything looks fine......although when i click on one of the buttons i get the next error: Not Found
The requested URL /PowerCMS folder/admin/contents_results.php was not found on this server.
I think this has something to do with the path although i did not replace anything!?
I send you a screen picture of the file-structure.
Peter
