[SOLVED] Plesk panel empty ? while sites are working

[Erwin Fiten]

Hi, I'm using latest 12.5 build of plesk (Web Pro edition) on Debian 8.
Until now it was working like it should.

When I changed to Power User view, a got to the login screen, after login in as root, I'm seeing that everything is gone ? I'm getting like a first setup page :

I have 5 domains on this server, that are accessible without problems.
But the backend seems to be gone?
Is there anything I can do about it? should I restart Plesk to see what happens ?
But I don't want the sites to go offline after restart, now they are still working but i can't go to the backend.
Untill now, the enduser doesn't see the problem, when i restart, and the sites are gone, they will notice it.

I asked a customer, and he IS able to login to the backend part of his domain, so this is strange.

Hi Erwin,

Could you check the content of your log?
/var/log/sw-cp-server/error_log and /var/log/sw-cp-server/sw-engine.log

See if there's any issue reported?

What I would do (I can't assure that it wont break anything but i'm really confident that apache/nginx etc will still run) is to run this command /etc/init.d/sw-cp-server restart and try again.

Restarting will i itry later today

You didnt get the result of the second file, there was a "and" between paths I sent.

Please provide result from "cat /var/log/sw-cp-server/sw-engine.log" too.

cat /var/log/sw-cp-server/sw-engine.log
is empty.

I can login as any user, and it works, user sees al his domains.
But when I try to login as admin or root I get the first screen from my mail.

Is it possible to give another user admin access by altering the database? so I can login to the backend again ? I really need to access it.

FYI, Plesk support logged in to my environment, created a new (dummy) site, and everything appeared again.
Then I deleted the dummy site, and it still works.
