Can You Change the Default Message?

Hello!

My membership plugin is working as it should.

I just wondered if there was a way to edit what shows up when you try to access a page that you don’t have permission to access.

Right now, it says ‘The content you are trying to access is only available to members. Sorry.’ and then there is a contact widget.

Is it possible to change that, and if so, where can that be done?

Thanks!

Tim
