I had been trying to set up a theme in Magento 2 several weeks ago and now when I try to continue the work, it seems that the CSS on the site has stopped working for my theme. The site loads without any CSS at all.
I have tried to clear the cache (and CSS merged cache) but it is still not working.
As I am still trying to get LESS figured out, I am wondering whether it might be some css I have changed which causes LESS to crash. Is there any way to determine if LESS is not working or what else the issue might be?
