I linked the newest version of bootstrap.min.css with <link rel="stylesheet" href="assets/css/bootstrap.min.css"> to my webpage.
Everything worked fine. But now my browser tell me that the bootstrap.min.css.map is failed to load.
My stylesheet link says that bootstrap.min.css is linked, not the .map
With <link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css"> everything works fine.
