503 errors

What has worked before if a 503 error comes up on a simple test PHP bit of code, is to disable and reenable cagefs, like:

[08:27:00 cpanel01002 root@9055583 /home/bangaqua/public_html]cPs# cagefsctl --disable bangaqua
[08:27:14 cpanel01002 root@9055583 /home/bangaqua/public_html]cPs# sudo -H -u bangaqua bash -c "php test.php"
