"Site Wide Subscriptions" icon Disappears when turning off "Post Subscriptions"

Hi Team,

I think there is a bug. I have "Site Wide Subscription" turned ON and it displays the "Subscribe via email" icon on the frontpage as normal. But if I turn OFF "Post Subscriptions" and click on a discussion, the "Subscribe via email" icon disappears and people can only see the icon again if the go back to the easydiscuss frontpage.

I don't know why turning off "Post Subscriptions" makes the "Site Wide Subscription" icon disappear?

Because if I have both "Site Wide Subscriptions" and "Post Subscriptions" turned ON, then I see the "Site Wide Subscription (Subscribe via email) icon even within the discussion.

I hope this makes sense and you can help out. I do not want my users subscribing to individual posts only site-wide notifications. And need them to see the "Subscribe via email" icon when in a discussion.

Can you please help? I have attached 2 screenshots to point out the icon I am talking about and the "Post Subscription" setting that when turned OFF makes the icon disappear within the discussion and only shows on the Easydiscuss frontpage.

Thanks
