A couple of weeks ago we configured apache https on our mailman server. Since then we cannot approve/discard/reject any messages using web interface - why? Does anyone have any idea?

The problem is the form actions are http url's. Apache is redirecting them to https and you are losing the POST data.

The FAQ I referred you to in my other answer refers to https://wiki.list.org/x/4030702. If you look at that FAQ, you'll see you have done step 1, but not steps 2 and 3 which also need to be done (step 4 is optional, but saves a redirect on public archive access.
