Hello, i am very satisifed with this host. There's just a slight problem. Every time a Person tries to sign up a big 503 error comes up. WTF? Im losing lots of registrations. Help?!?
I am using Anahita Social Engine

That's weird. I still have the issue. I uninstalled various mods and nothing. Contacted Anahitapolis and they said its a problem with the host. Help? Forgot to mention that Anahita is based in joomla 1.5 just in case. And it happens only on registration. Its really weird.
