Enable Xdebug for Subdomain Only on Plesk

Question

I’m running Plesk 18 on AlmaLinux 9.5, and I have a domain – let’s call it example.com – with a subdomain dev.example.com.

I’m trying to enable Xdebug only for the subdomain.

Under the "Additional directives" section for dev.example.com, I’ve added the following:

[Xdebug]
zend_extension=xdebug.so
xdebug.start_with_request=yes
; etc.

I’ve restarted both the web server and the PHP service.

However, Xdebug doesn’t seem to be working. Is there something I might be missing?

Thanks in advance!

• Tyrsson: We need to know what version of xdebug at a minimum. I would really spend some time reviewing the xdebug doc site so that you can secure your debug session. This is a good place to start. xdebug.org/docs/step_debug
