Easy to miss, but the “prefix” in zogstrip’s post is not in monospace. i.e. it is not part of the setting name.
What was said is "
category page style" is now “
desktop category page style” in prep for the coming “
mobile category page style” setting.
Anyway, I have two localhost versions of Discourse, latest and 1.6.0beta9
The 1.6.0beta9 version does not have a “
category page style” setting.
It does have
category style, but that is bar, box, bullet.
It does have the newer “hybrid” categories page. but I could not find any setting.
Things have changed since that version so there very well could have been a setting that was there between then and now. (Or maybe “top menu” took “classic” ?)
In any case, rather than hunt down a setting that may or may not be there, why not upgrade to latest?
