Hello,
It looks like that there is a problem with your PHP sessions, can you share the exact steps that you’ve taken to install the control panel?
I will also suggest checking your PHP sessions to make sure that they are configured correctly. You can do that in the php.ini file.
Hello, @sihongof
As per the previous reply this sounds like PHP sessions issue. Another option will be to access all of the control panels using alternative browser in order to confirm that the issue is still persisting.
Installing cPanel/WHM, Plesk and Directadmin as one-click app should work just fine, so let us know if you’ve installed them manually or as per ServerEnthusiast share the exact steps that you’ve taken.
Regards, Alex
