My XF installation has been running fine for over a year. Today, I realized that my approach is completely wrong for SEO and for simple organization of subnetworks (WP). Currently the board URL in the admin panel is set to http://www.technologyquestions.com/community However, the actual domain is www.tuxreportsnetwork.com in which technologyquestions.com is a mapped domain through WP. Everything is accessible. But it is also accessible from any of the domains that are mapped. While restructuring the menus on the WP side, I realized the appropriate way to reach the community is http://community.tuxreportsnetwork.com and nothing else should be getting to it. The frontpage loads but if I click on a link then there is an 500 internal server error. How do I set this installation up so that community.tuxreportsnetwork.com works? This is the current config.php (minus host, port, passwords, etc). Code: $config['cache']['enabled'] = true; $config['cache']['cacheSessions'] = true; $config['cache']['backend'] = 'File'; $config['cache']['backendOptions'] ['cache_dir'] = '/pathto/tuxreportsnetwork.com/community/internal_data/cache'; $config['cache']['frontend'] = 'Core'; $config['cache']['frontendOptions']['cache_id_prefix'] = 'xf_'; $config['cache']['backend'] = 'File'; $config['adminLogLength'] = 30; $config['superAdmins'] = 'xx'; Note: Because of the XenScript add-on, all users must log in through XF. This also means login for each of the WP domains. This restriction means I cannot forward everything to community subdomain. Does that make sense? So, the solution must be something to get community.tuxreportsnetwork.com to work and I can hard code menus to always point to that domain. Maybe then block search engines from crawling via the other domains. Correct? Update: I looked in the error logs for the server. Code: [host community.tabletquestions.com] [client xxx.xx.xxx.xxx] Request exceeded the limit of 10 internal redirects due to probable configuration error.
