This happens when I try to add a new domain or when I am trying to remove a domain. It just hangs, the browser says waiting on server while plesk just hangs. This is a fresh new install of Plesk 12 as well. I added a bunch of new domains tonight. No crazy changes or anything to plesk. Does anyone have any sort of idea what would cause this? I have found nothing so far in my search. Any help would be greatly appreciated.
