Attention
If your Photo Cart is suddenly getting a 500 error or only displaying a blank page then you or your hosting company has updated the PHP (programming language) to PHP 7 which Photo Cart is not compatible with (and will not be compatible with) mainly because of the removal of the my_sql functions which are replaced with my_sqli functions.
You would need to have the PHP version downgraded to 5.6 in order for Photo Cart to work. If downgrading the PHP doesn't work then you may have to update Photo Cart to the last version of 7. Download Photo Cart 7 upgrade files. Upgrade instructions.
Photo Cart was retired in 2015. Check out Sytist.
Photo Cart Versions 5 - 6.1.3 Security Patch
You can check your version of Photo Cart at the bottom of any page in your Photo Cart admin.
To Fix:
Download this zip file:
http://www.picturespro.com/sy-misc/download/Photo_Cart_5_-6_Security_Patch.zip
Included in the zip file is a "_login.php" file inside the admin folder. Upload that file from the included admin folder INTO your Photo Cart -> admin folder on your website overwriting the existing one.
Or upgrade to Photo Cart 7
This is not an issue in Photo Cart 7 and is a free upgrade.
