I have a temporary solution..
If you have a FTP setup, then go to your directory.. (blog)/wp_content/plugin
and then rename your PageFlip folder.. That should fix the problem of the whole site being down..
BUT, if you impletemented page flip on your site, those wont work.. Atleast its better than the whole site being down :S
Now I dont know about the plugin whether there will be a fix or not..
