I have installed the software myself and it's configured to be shown in the index in the bottom. Nothing is being displayed, the servercache has been cleared but with now positive outcome.
My Phpbb Version 3.1.3
Check the folder called: mchat/styles/prosilver/template/event
And make sure all the template files got uploaded to that event folder, there should be 5 HTML templates listed in it but me and another person found when uploading the mod that they didn't all get uploaded for some odd reason first time around
Sounds like you've had same problem also, all the templates didn't get uploaded
