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.
Clients Not Getting Emails To Msn Addresses
However, if I email from my domain through outlook to those addresses I can get through. I am using the same email address that is set at the default in photocart. It used to work at one time but it doesn't seem to be working any longer. My email configuration has not changed in years and neither has my hosting.
Is there something that has to be modified somewhere? Typically when MSN blocks godaddy it blocks both my email from outlook and the server email from photocart. I am moving servers in the next few month so I hope I have better luck but was just wondering of there was any other solutions.
