I just installed and started using Drupal 7, and I followed the instructions to turn on Clean Urls. I clicked "Run the Clean URL test" button, but it failed to return any results. It loads up something and then refreshes the page.
Can anyone shed light on why this is happening and what I can do?
Sometimes somehow the opening up of the cleaned URL page fails and does not display an error (as I guess from the perspective of the system there is none). Try to manually change the URL from:
www.mydomain.com/?q=admin/config/search/clean-urls
to:
www.mydomain.com/admin/config/search/clean-urls
And see if it displays the checkbox, of it does, select it and save.
