  • The BIND DNS server has already been deprecated and removed from Plesk for Windows.
    If a Plesk for Windows server is still using BIND, the upgrade to Plesk Obsidian 18.0.70 will be unavailable until the administrator switches the DNS server to Microsoft DNS. We strongly recommend transitioning to Microsoft DNS within the next 6 weeks, before the Plesk 18.0.70 release.
  • The Horde component is removed from Plesk Installer. We recommend switching to another webmail software supported in Plesk.

[SOLVED] Plesk panel empty ? while sites are working

Erwin Fiten

Erwin Fiten

Basic Pleskian
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 :
plesk.png


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.
 
Code: 
root@fiten:/home/efiten# cat /var/log/sw-cp-server/error_log and /var/log/sw-cp-server/sw-engine.log
2016/02/28 12:59:36 [error] 20269#0: *513 open() "/opt/psa/admin/htdocs/robots.txt" failed (2: No such file or directory), client: 66.249.78.154, server: , request: "GET /robots.txt HTTP/1.1", host: "www.on6zg.be:8443"

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.
 
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.
