This is not an issue with slick theme, it was related to a bug in core https://github.com/NodeBB/NodeBB/issues/6306dangerusslee created this issue in NodeBB/NodeBB closed Some bootswatch skins broken #6306
Skins in ACP wont load; clocks forever
Just opened a new server with Mongo, it is 0.9.2. When clicking on themes or custom CSS it works fine. But, when clicking on Skins it just clocks forever. By forever, I mean that I left it up over night.
@bitspook there is a problem with bootswatch API. It's fixed in latest master.
Awesome, ok. Thought I was losing it.
