Hello,
Using MediaWiki 1.26.3 and CategoryTree 2016-01-09T22:52:17, I'm using it in the sidebar with $wgCategoryTreeSidebarRoot = "myRootCategory";
I'm quite happy with that but when clicking on the blue arrows, nothing is happening.
I read the doc and tried the workarounds, but to no avail.
I'm not using redirects or short URLs.
Our setup is very simple and common.
Is there something I could try?
Thanks for your help.
