Congrats on moving over to the forum.
One of the things I wanted to do with my version of the theme was to limit the max container width to some thing smaller than 940px, more like 880px. So i went off and got the most recent bootstrap. Before I started messing with column widths I just tried to regenerate the existing bootstrap.min.css.
I downloaded the most recent bootstrap and I installed nodejs, npm, less , jshint recess and uglify-js. When 'make' generated the two css files, bootstrap.css and bootstrap.responsive.css, I uploaded the latter to my server hosting 'the-bootstrap' theme, renamed to bootstrap.min.css (which I think it is). I was expecting everything to look the same, but the result is a page that looks like it has no css applied.
I investigated the css files and it does look like a css sheet, it just won't link to the theme.
What is your flow for generating the bootstrap.css, is it different from how I described?
