How do I enable error reporting or PHP debugging in WHMCS?

Question

I'm getting an error on my WHMCS website. How can I get more insight as to what the issue is?

Answer

You can enable error reporting in the WHMCS dashboard or configuration.php. You'll want to disable it once you've finished troubleshooting.

WHMCS has a guide on how to do this here:
