BuddyPress Group Email Subscription

We ran into an issue with your plugin – possibly due to it not being updated ni 12 months – message below from BuddyBoss:

For some reason the ges.subject is returning empty, you can contact the plugin author regarding this, in the meantime, I changed the title to “[<a href="http://site.name/" target="_blank" rel="noreferrer noopener">site.name</a>] {{poster.name}} posted {{activity.type}} in {{group.name}}” and now all the emails are having the right title.
