Ok sorry for taking so long as I now see the issue, but do not understand why it is happening.
It only happens if you use just osageroost.com and it's the redirect causing it. I'm a Mac user and safari has no issue with that. Google Chrome gives the Internal Error.
Ugh Browsers... Anyways I'll be working on trying to resolve this and not sure why it just started happening :-( The redirect is adding www at the end of the link instead of the beginning on some browsers!
Once again sorry for taking so long. It took us a while to track this one down :-(
