What do you do when you try to access your drupal site from school and all you get are blank white pages with no source and the absence of any 404 error or whatever? You promptly go outside, and smoke a dozen cigarettes, unless you just quit, then you clench your teeth together and freak out as quietly as you can. Then you go home, and realize that your page.tpl.php file had the wrong permissions and everything is soo happy, all the data is still there, all the sql tables all in their right place…ahhhhhhhhhh. But you still don’t get to smoke.
