Hi,
I notice (and others) there is a problem with thread subscription.
The solution is described on (forum admin only):
https://community.mybb.com/thread-223732.html
I also managed to subscribe to thread using a little workaround (Example for latest thread "Sub 35, few programme questions" )
1) After clicking "subscribe button" change "usercp2.php" to "usercp.php"

It will take you to subscribe page. Before clicking "Subscribe to Thread", you have to select Inspect option (I am using Chrome - right click -> Inspect) and you have to change "usercp2.php" to "usercp.php" in Inspect window:
