Internal Server Error on new install - every link from main page
 

Fresh install. Main page loads, but I get the below for anything I try to click on (login, FAQ, Blogs, Groups, etc.). Is the .htaccess file modified during install? I ahve tried the original upload file, the one in the DNR/rewrite folder, all with the same results. Thanks!
