Besides the host who kicked me off their shared servers, another host (Web750.com) tells me I'd have to go on one of their managed dedicated hosts. But Hyve.com and BlueGravity.com are willing to work with me to solve any problems, so I'm likely to go with one of them, and keep the other one in mind if problems arise.
bizzar528, I'd only gotten my site back up a few months ago, and I hadn't figured out exactly what I was going to do with it yet. It's a personal site, so I didn't have users, and there was only one database, which was for PHPNews, and I had two short articles in there. Barely anything.
Acecool, I'm not saying you're wrong, but the host said it was my site. However, I never saw the log.
DA Master, it wasn't a dedicated server, it was a shared server. They said I'd have to sign up for their dedicated server if I continued using their service.
Moronovich, thank you for your advice and info. I'll check when I have a new host. I don't think anything was wrong in the included files; they were very simple files, consisting mostly of HTML.
