Available Lists is empty

Hi guys,

This plugin was working well then I updated my mailgun API keys and forgot to update them in the plugin so of course it stopped working.

Now I have entered the updated API keys in the plugin subscription is still not working from

I dont think the plugin is hooked into and mailgun list as I can’t see that in the settings page and available lists is empty.

Any help would be appreciated. Cheers
