Where can I get a list of paths for my domains? like where PHP lives, etc?



I don’t know of such list, but you can easily check the paths if you log in through ssh.

Turn ssh (Secure Shell) access on in the panel (if not already on) for your user and log in using ssh. Then, run the command which php. Instead of php, you can use any command you want.

For php, I think that you can also use a phpinfo file to find the path.
