Also, I’d like to add that the corresponding parent display tabs also disappear from the main group menu when you select tabs in the admin submenu, But work fine (do not disappear) when you select them from the main group menu. Seem like issue only occurs with the function edit_screen() in the admin submenu.
I agree, and no they are not sharing IDs or slugs. I’ve been chasing this issue for months now, and just today realized it had to do with include sequence.
I’ve also noticed the behaviour in other plugins, such as the BuddyPress Group Email Subscription by Deryk Wenaus, boonebgorges. If that plugin is activated also, it will interact with the tabs from my plugin hiding tabs etc. Low and behold, they too are using the BP_Group_Extension API.
Wonder if this is a bug? I also tried it with a virgin install of WP and BP and it happens there as well.
Have you found out anything else about this? I need this feature as well. WIth the admin bar off there are no notifications of invites other than via email. I’d like a visual indicator of the pending group invites (count) that I can display in a dashboard plugin I developed.
