When trying to install Simplemachines Forums:
Cannot connect to the MySQL database server with the supplied data.
If you are not sure about what to type in, please contact your host.
Unknown MySQL server host 'sgco.stgeorgecathedral.org' (1)
I've even deleted and recreated this mysql db just to make sure there wasn't something weird stuck in there. I also tried putting http:// in front but that didn't work either. Prior to trying to install this, I had WordPress working fine with that database.
