Consider it a hit and miss with the hosting and move over to another provider.
Godaddy is very well known, but it's sucky in my opinion. I hate dealing with them. I just use them as a domain look up.
I highly suggest that you get a hosting account with
http://www.arvixe.com/
I've been with them for years, and they're really good. Their support is good, and they always fix any problems I have. They support 100's if not 1,000's of scripts.
Mysidia generally works on it. (I've had the login error once, then reinstalled and it worked). I've had Mysidia running on this host a few times.
You can also change the php version for each folder, so you can have multiple websites on the same host, using different scripts that require different php versions.
They also give you a free domain upon registering. So while you may have the .com now, you can get the .net as well, so if your website becomes popular, no one can register the .net and steal your traffic. (They also have great backup services and free privacy for domain names)
I sound like an ad, I'm sorry. I just really love my host D=
