This is a discussion on Restart file within the Theme packs forums, part of the nukemods releases category; I got a question,
for php-post you got the file psak.php to restart your website with a different theme if ...
Ok im not sure if this will help you but i figured it out on my own site and got everything back to normal. Here is what I did.
and this may vary depending on your host and your ftp access
IF you have ftp access find this path /public_html/then your site name/header.php open this file so that you can edit it. find function head() { and then scroll down until you find these lines. the red is what you need to replace. where it says get_theme. change only what is in the (). this worked for me hope it works for you.
