So no issue on the login request...
The output is ok! Need more time to understand why you have this issue.
A way would be to re-upgrade manually to version 18-1 (maybe fvdw-sl is corrupted), and see if you still have the issue.
So download the package from https://plugout.net/viewtopic.php?f=7&t=3084and upload the zip file extracted from the rar archive
Did you made some changes on php config ?
no...no changes..
i installed Firmware 18-1 again..
rebooted
Error comes again..sorry
