Drupal Doesnt Load after Installing Theme I had installed Omega Theme in drupal. I enable and set it as a default theme.I also disable it's former default theme "Bartik". Now I didnt see changes taking place in my Drupal site. Because of impatience I exit the browser and  loads drupal again but it doesnt work like before. I cannot access drupal anymore and shows only white page just like the image below. 



What shall I do to fix it?
Start by re-downloading the theme to eliminate file corruption as a possible cause. Can't say how to fix the site without knowing what's happening- If copying the files doesn't work, enable error reporting and troubleshoot from there.
