404 and 500 errors in django

Problem: Server Error 500. In the server log, all it mentions is a line that looks something like "GET / HTTP/1.1" 500 27 Potential fix: There are two potential reasons for this error.

First, PyPI says that django-less is not maintained and suggests using django-static-precompiler instead. Second, while LESS suggests that the easiest way to install the compiler is via npm, it is just as easy to install the LESS compiler via nodejs-less.…Read more …
