domain-name.com/user and other URLS not loading When I go to my domain.com/user I get a blank page, where as usually that was the URL  I go to to log in and change content. I came across this thing: https://www.drupal.org/node/256410, but I do not know if it is the same issue. I tried uploading a new .htaccess file to no avail. Any thoughts/ suggestions?
You should enable apache's rewrite mod. and then restart your apache server. 
Then, goto configuration and check clean URL. After that your site will be using clean URL.
