How to get same Forum design (blue) as showed in your plugin page ?

Hi There, I found your forum in your plugin page which was looking great but in my site it doesn’t look at all like the one showed in your page :slight_frown:

How to get the same design as showed in your plugin page please ?

This is the way I was wondering to see the Forum in my site: https://premium.wpmudev.org/wp-content/uploads/2008/08/forums1.png

Thanks a lot,
