Changing a server is never a totally peaceful task, especially when the causes involve data corruption. At this time, it was a machine with Linux and Plesk Control Panel 9.x
After the server and upgrade of the panel version, I was unable to get access and even assign the directory permissions to the statistics page
https://meudominio.pt/plesk-stat/webstat/
Plesk stores usernames and passwords in the folder
/var/www/vhosts/meudominio.pt/pd
and so far, so good. But when trying to go to
https://meudominio.pt/plesk-stat/webstat/
and correctly placed the username and password, it never authenticates.
The problem is in folder permissions
/var/www/vhosts/meudominio.pt/pd
which in this case was user:psacln and must be root:psaserv.
Running in shell
chown root:psaserv /var/www/vhosts/* /pd
solved all the problems.
Did it work for you? Please leave your comments below.
