The problem I have at the moment is I cannot even start doing anything. I still don't have access to my WHM/Cpanel backend since the hosts server has issues. And when I ask my host for help, they just say they have rebooted the server. Then the problem reappears. I hope it resolves itself.
Been on and off with support all day. Finally managed to get someone to do something. They said I needed to upgrade cpu and ram, but that is nonsense. The site normally runs fine. Anyway, they unblocked me from logging into the backend. So at least I can work on stuff now. Let's hope the issues go aw, so I can work on the resolution to these problems.
I noticed things slow this morning too with a very large number of guests, which is highly unusual. Same issue last night, with about 3000 guests. We normally max out at about 600. Perhaps someone is attacking the site.
I've just changed some backend settings and it immediately got faster. Lets see if it stays that way.
