Error: Undefined constant "showBackground"

#0 /var/www/html/inc/actions.php(27): include()
#1 /var/www/html/doku.php(126): act_dispatch()
#2 {main}

Solution:

• Added a $ in front of the showBackground support constant to make it a local call.

Could this be the real fix, or is there something bigger here?
