For years I’ve been using the Admin Bar so that I could see which new forum posts were unanswered. I’ve always been able to update this plugin without any issues. Now it seems Simple:Press has changed their licensing system.
I was using simple:Press 5.xx and Admin Bar 1.3.1. I updated Simple:Press to 6.xx, which caused the Admin Bar plugin to break. It said that I could update the Admin Bar plugin for free to version 2.2. As soon as I did that, it said that version 2.2.1 is available, but that I need to purchase a license to update any further.
My problem is that the PostBag is no longer working. When I am viewing the forum on the front end, the Admin Bar is currently telling me that I have 6 unread posts. I clicked the “View New Posts” button. A window expands underneath, but there are no posts listed where there normally should be. All I see are the “Empty the Admin PostBag” button and some text “New/Unread Posts Management” See screenshot:
I’ve tried disabling every other plugin on my website, and switching to twentyninteen theme, this doesn’t fix the issue. Do you know if I purchase a license so I can update to 2.2.1, will this fix the issue?
