How to change the domain settings - getting "access denied" error

I have the video tutorials installed on my multi-site network and am having issues getting them to display on my site. I get the "Access Denied, Please Check Site Registration" error. I am assuming this is because I put in the wrong domain name when setting it up, but I can't find how to reset that and put in a different domain!

When setting it up, I put in my main network domain,, but the domain I'm trying to display them on is actually one of my sub-sites, domain - so I'm assuming I need to change the domain to match the site I want to display them on?

How do I change the domain? I don't see anywhere in the settings to do this...

Thanks in advance for any help you can offer! :slight_smile:
