Hi Eduardo,

I used this very good tip on the top of the page (disabling the “prefer plain-text” option), however I recently started to get the same problem again (evolution 2.22.3.1).

I then tried to mark the “prefer plain-text” option again, and everything suddenly started to work; buttons showing and everything fine (after clicking another mail than the one I looked at). Perhaps it will work for you too?

I didn’t post anything in the bug you mentioned since I don’t have a login there yet. But hopefully people read here too. 🙂
