I have followed the search engine friendly steps provided by including the rewrite rules in .htaccess and set the default templates to search_engine. Clicking on any of the links from the main forum page leads to a 404 error. I have tried to find a solution in 'Search Engine Friendly Templates!' thread but I have had no luck. Is this a common problem? Is there a common solution to this? This is a pretty fresh install so everything else should be default.
