Hi Marc,
Thilanka,
with the same scenario, at the same point I now see:
Warning in ./libraries/common.lib.php#2917 Cannot modify header information - headers already sent by (output started at server_privileges.php:1440)
Backtrace
./libraries/common.lib.php#2917: header(string Cache-Control: no-cache) ./server_privileges.php#2296: PMA_ajaxResponse( object, boolean 1, array, )
I fixed the issue of giving warnings regarding the header modification, and updated the repository. Please can you check that. Thank you.
Regards, Thilanka.
