UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Adding gallery and regular subforums to same parent forum

Is it possible? I "see" the regular forum enabled in the CP, but only the Gallery subforum is visible on the board.

Is it something I am doing wrong with permissions, or are the two subforum types incompatible?

Ver. 7.3.1
