TypeError must be str, not bytes

You do a nice job with django-inlinecss.

I have a question, when I try to send the email with django-inlinecss it appears the following error: "TypeError must be str, not bytes" in line "{% inlinecss" demo / demo.css "%}". How can I fix this error? Thank you very much and sorry to bother you.

I had the same problem, it was caused by Django not being able to locate the css file for inlining. Check that the path you gave is correct and make sure that your static files are being correctly served for whatever your DEBUG mode is.
