Hallo Axel danke für die Antwort. look at php and http error logs to find out what goes wrong. We do not have much experience with instalations on Raspberry but it seems to work. give us feedback if you found the problem ich habe die logs geprüft. Da ist kein Fehler. check the following: if mysql : lower_case_table_names = 1 php.ini : short_open_tag = On das ist so. check authentication sql query in lib/session_auth.lib line 170 - (error_log($sqlquery2);) check the following lines in lib/session_auth.lib...
no login after installation
