I logged in to the admin's panel and went to the management tab to view a couple things. However, when I click on settings in the server folder, it gives me an error saying that the page might be temporarily unavailable. It does the same for everything under the system config, form designer and server folders.
I then went ahead and restarted the ispconfig server by issuing the command
/etc/init.d/ispconfig_server, and it restarted without any problems. I tried going back into the management panel, but it acted the same way when i tried to access those links again.
Any reason why it, just all of a sudden, would act like this? I've had it set up for about a month now and never had any issues.
