There is a bug in the interaction between sub-sub-categories and the navbar.
I’ve got sub-sub-categories enabled on my site via this hidden setting:
SiteSetting.max_category_nesting = 3
After our last update of the site, the functionality seems to have broken.
The sub-sub-categories appear as they are meant to throughout the site, but when I attempt to click onto one of them I notice this:
The category page seems to load just fine initially
Then I get the spinning wheel of doom
This error appears in the console:
(this doesn’t appear when in categories or sub-categories)
Workaround / other issues
The sub-sub-category page actually loads okay if opened in a new tab/window, but there are glitches in the navbar functionality and this similar error in the console:
This is a theme component right? Which one is it, can you link to it?
Ah - I’m being a bit thick and equated the new terminology for the sidebar “i.e. Navigation” with this official theme component:
When I disabled that Theme Component, nesting works just fine.
My only issue is that I really rely on it! But I understand that I’m probably one of very few using this TC with 3rd level nesting.
Will mention this to Kris in case he has any easy ideas for a fix.
This is fixed by: FIX: update to support 3 levels of categories by awesomerobot · Pull Request #6 · discourse/discourse-categories-navbar · GitHub
I just needed to make a small adjustment to accommodate for the additional category level. Thanks for reporting it!
