I am a moderator on the 000webhost forum (which of course, runs Discourse).
The issue is that on maybe half of the topics, I cannot choose the solution. It doesn’t matter if it is a topic I created, or someone else’s that I answered. Whether I replied or not, the icon to choose a solution only appears on one for every two topics. Is this my error, or a site setting (I can always ask an admin to change it if it’s the latter)?
