ISPConfig stopped working
I had ISPConfig up and running for a couple months without a hitch. Everything worked perfect. The server became unreachable just the other day so I had to reboot it. Now ISPConfig doesn't work! Apache, MySQL, PHP, etc... seem to be working fine, but ISPConfig doesn't come up anymore on port 81. Here is the URL:
nothing changed on my router - I get the same error whether I'm inside or outside the router...
Any ideas of what could cause this? Where do I start?
