To enable search-engine friendly URLS, copy this ".htaccess.txt" file to the osDate root folder, and rename it to .htaccess You must be using the Apache web server with the mod_rewrite extension enabled to use this feature. Please note that this... # Replace with site url prefix RewriteBase / ... should be replaced with your "docroot" setting from config.php, if different than "/". For example, if you have osDate installed to a sub-folder called 'osdate' (i.e., your docroot is something like "/osdate/"), then this value in htaccess would be changed to: # Replace with site url prefix (note: this is case-sensitive!) RewriteBase /osdate/
