Description: I can't remember what HTML is suported, so I tried http://sensibleendowment.com/sandbox.php

Whether clicking the link or navigating directly to that URL I get this error:

Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/sensiblehome/public_html/sandbox.php:11 Stack trace: #0 {main} thrown in /home/sensiblehome/public_html/sandbox.php on line 11
