Urgent Help. Blank website.

I have had my website in maintenance mode whilst I deactivated some of the categories and products. Last time I worked on it it was working fine in maintenance mode and I was able to view the store front fine. Have just gone to put it back online and I now have a completely blank white page when I go to my website both online and in maintenance mode. No error message, just blank.

Please can anybody help as I have customers waiting to order.

There's always an error. Set Display Errors to Yes or uncomment error_display option in php.ini to see the error.

Am not good at this but have done that and got the following ...

Notice: unserialize() [function.unserialize]: Error at offset 0 of 2 bytes in /home/lemonie/public_html/stinkytink.co.uk/admin/controller/common/footer.php on line 1

No, no no, this isn't even an error, this is a notice. Notices can never break your site, only errors and warnings. Should be something else.

You may try to look into error logs right on your server via FTP or in cPanel or whatever admin software you have with your hosting provider.
