How to 'undo' site redirect?

I inherited a school website from another webmaster whose student has graduated and moved on, and who is not available to help me.

We have two domain names: [baseball-team].com and [baseball-team].org.

He has the .org forwarding to the .com, which I would like to reverse or at least undo, but I cannot figure out where the code is that is causing this redirect to happen.

I’ve looked at wp-config.php and the root .htaccess file, but it does not appear to be in either place (although i admit I’m a novice so perhaps it’s there and I just don’t see it).

Can anyone help? I’ve been looking for two days. 🙁

Thanks!
