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.
Mail Not Sending And No Error Logged
Everything is working with the exception of some emails. The test email feature from Website:D's settings page works fine. But posting a contact entry does not. It seems both are calling the same function to send the mail, which ultimately uses mail() based on his site's settings.
In PhotoCart settings, sending a test mail does not work - no error is logged, but the recipient (Dave or myself) never gets the message. Also, if an order is submitted, the notification email is not delivered.
I'm still digging, but thought I'd ask here for any ideas of things I can try/look at?
I put up a simple page on the site that just uses mail() to send a message, that works fine. The fact that any are working seems to rule out a hosting issue or even domain propagation issues (DNS change was just over 24 hours ago at t his point, and https://www.whatsmydns.net/#A/davidjstudios.com indicates most of the world and certainly the US knows about it).
