I am forced to use PHP 5.2.17 for now while we work on a site upgrade. OSTicket v 1.7.0 has been working perfectly for years until midnight UTC on Feb 28. Now, the pipe rejects all emails and in the error log I receive this:
Call to undefined function mysql_connect() in /ticket/include/mysql.php:26
My legacy site uses mysql_xxx functions everywhere and it works just fine with no errors thrown. The ticket system is under a subdirectory within the legacy site: public_html/mysite/admin/ticket/xxx
I am not sure why the ticket scripts are throwing this error, I can send emails from the ticket system and everything else is working, it's just piping no longer works.
I have not made any changes to the server, PHP, files, anything. It just suddenly stopped piping. Please let me know if further info is needed to help figure out the issue, I am unable to use our ticket system anymore.
