I added an if statement around the content render php in my page.tpl.php file. Only problem is I made a mistake and accidentally prevented it from rendering content on any page. I cleared the cache and logged out to test it, and realising my mistake I corrected the template file. But now I can't log back in to clear the cache again as my site won't render content and thus won't render the login box.
Can someone give me a way in Drupal 7 to either log in without the login in box (like a way to render the login box separately to the content) or a way to clear the cache?
