Here a solution that worked perfectly for me, from ‘Tylersoden’
If anyone stumbles upon this thread and is interested in a css solution, here is the code I use. It goes in the ‘Appearance’ -> ‘Editor’ section on the wordpress control panel or in ‘~/<your theme folder>/style.css’:
.bbp-template-notice.info { display: none; }
Thanks tylersoden mate, this worked perfectly for me! 🙂
