Bootstrap subtheme does not recognize stylesheets I'm trying to use a custom (LESS) build of Bootstrap in my Drupal project. I have a subtheme in the proper folder and have compiled a style.css file. However, Drupal does not recognize this file. So far I have 


Edited the .info file to switch of the CDN and switch on the local .js files
Cleared the cache
Switched off the aggregation of CSS
Restarted the server
Added a foo.css to the .info file for testing


Nothing of this works. The subtheme does not recognize my custom css files. 

What could have gone wrong here?
I forgot to turn the subtheme on in the theme settings.
