When I initially try to access the spanish version of my site, I'm presented with a blank page with a "Forbidden Access..." message. It says my ip address is suspicious and asks me to click a link (>>>>>>) to proceed.
To reproduce the issue go to http://nghd.org
and click the "en Espanol" link in the upper right corner. This takes the visitor to http://es.nghd.org
but they first see the "Forbidden Access..." page.
I have another Enterprise account at http://northgawic.com
and I've never been presented with the "Forbidden access..." message when accessing es.northgawic.com and I'm using the same PC on the same network.
