Can you give me your configuration, it seems related to how you have configured the backend.

[BooBSD]

Sure, here it is:

BASE_DIR = os.path.abspath(os.path.dirname(os.path.dirname(__file__)))
rel = lambda pth: os.path.join(BASE_DIR, pth)

I can not reproduce it. Are you checked that with the last version of django_jinja ?

PS: you have both match_regex and match_extension in settings that are completelly redundant, keep the extension and remove the regex based.

[niwinz]

Ah, ok, that should work with the last version because some related errors to regex are fixed.
