I'm having an issue with a custom module I built.
The issue is that when I click on "settings" to go to my custom setting for my module that I built it just sits there with the loading popup indefinitely and I don't know what's wrong.
It used to work and work well, but something's changed and I'm not sure what has changed...

Has anyone had this problem before? If so, how'd you fix it?

Thanks in advance and best regards,
Marco
