Unable to enable 'Enable board URL canonicalization'

[nodle]

I did an import tonight and was getting everything setup, but for some reason I am unable to enable 'Enable board URL canonicalization'. When enabled it get the error "To many redirects" and just a blank page. I can't quite figure it out. I have the website address correct in Board URL. I did move my forum to the root and I have checked .htaccess along with config.php and everything looks good. Anyone have any ideas on what I might be missing? Thanks!
