Created attachment 61928 [details] Remove "index.html" to enter When you enter the administrator with the corresponding credentials the following error appears: "Error: You do not have permission to access this page." But when deleting "/index.html" from the url starts normally.
It looks like the login page knows (based on browser cookies?) when you have been previously logged in successfully. If I start with a clean session I get no message at all. If I log in, log out, and then return to "[domain]/index.html" I get "Error: Session timed out. Please log in again." However, I was not able to reproduce the permissions error you cite above. Tested using kohadevbox running master.
I cannot recreate. We had something similar some months ago (I cannot find the bug number), so it is certainly fixed. Please reopen if it happens again.
