I have this issue as well. Maybe my contribution will provide some movement and a closer find to a fix.
I am using a custom template that is a cnp (which I plan to edit) of the FORUMDISPLAY template for specific forumids.
I discovered that the statement below does not work:
PHP Code:
<if condition="$show['forumslist']">
However, if you replace the
forumslist with
quicksearch it will like below:
PHP Code:
<if condition="$show['quicksearch']">
So some variables are not included in the template, so you have to define them somehow.
Further information and details can be found at this
thread.
