Prestashop Stopped Working - Blank Page

[Fazza09]

Hi!

I tried to implement my shared SSL certificate but when I did so my website stopped working - just a blank page when going to the website and an error when trying to get to the back office part saying "

“Current theme unavailable. Please check your theme directory name and permissions.”

I edited the Link.php and init.php files as per this thread here:

http://www.prestashop.com/forums/viewthread/12819/installation_configuration___upgrade/ssl_certificate__shared_or_dedicated/

I have copied the original unedited files back but the problem still exists - a blank screen when I go to my website.



Anyone any ideas how I can get back online?
