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.
Users Unable To Login
I thought maybe something was buggy with my customer info so I created another account. I placed a test order and received email confirmation of it. When I tried to login as that customer after placing the order, it simply bounced me back to my entry page with the option of logging in, rather than with my account info.
Both of these attempts were made from my iphone.
When I try to login to my account from my laptop, I am given an "untrusted connection" notice from my browser. The details state that it is an invalid security certificate.
But either a) You don't have a SSL installed or b) You did but it has now expired.
Either uncheck that option or have your SSL renewed with your host if it has expired.
