Tags Search Redirection

"Too many redirects occurred trying to open “http://utahdogs.com/pg/search/?search_type=tags&q=parks”. This might occur if you open a page that is redirected to open another page which then is redirected to open the original page."

When I click on a tag in a page I get this error... my install is pretty new, 1.7, and I'm not familiar enough with it to really trouble shoot. Anyone have any advice? Thanks.
