That tip alone should be a sticky somewhere. Always, always, always make more than one backup before a move.

1and1 is horrible nowadays. Check webhostingtalk.com and search for them. They were excellent a few years back, but are completely in the gutter now.

For VPS, I can't say enough good things about powervps.com. They've been my host for over a year now and their customer support is absolutely outstanding. I had some server issues last week, and the owner actually called me and chatted for half an hour, hashing out ways to go about resolving it. That kind of CS is unheard of these days. They're really fantastic.

The problem here is some of your hacks / mod installs seems like you have the thank you hack installed if so uninstall/disable it will kill any forum with a large amount of users unless you purchase a dedicated server.

Please list the hacks/mods/packages you have installed.

If you need a dedicated server you can purchase one here

The pricelist can be found here for the servers.

Mostly for gameservers/dedicated gameservers but also servers for individuals that want to do their own web hosting or need more power that a VPS or shared hosting account can't offer.

You will get the same thing if you move to another shared host. Dreamhost is very friendly and open with their customers on what they can and can't do (flexible)
