TemplateDoesNotExist at /admin/ admin/index.html

I am unable to access the admin interface in django 1.1.1 using localloop:8000/admin. It was working fine on Ubuntu 8.4 then I upgraded to Ubuntu 10.10 and the problem occurred.

In settings.py I have:

import os.path
PROJECT_DIR=os.path.dirname(__file__)

TEMPLATE_DIRS =(os.path.join(PROJECT_DIR,'templates'))

This was working fine on Ubuntu 8.04 but not in Ubuntu 10.10.

Any ideas on what goes wrong? Here is the traceback:

Ensure that APP_DIRS is set to True in the Templates

Hmm, that's odd since TEMPLATE_DIRS setting doesn't have anything to do with the admin app.

If you're sure it's those 3 lines, the only possible thing I see wrong is TEMPLATE_DIRS is supposed to be a tuple (yours is a string), but on 1.2.3 it doesn't cause any problems.

You say "the problem occurred in settings.py"... but I don't see where a TemplateDoesNotExist error would appear from the lines you pasted -- can you post the full traceback? Which line of code triggered TemplateDoesNotExist? How do you know it was settings.py?

I think the problem lies outside of your 3 lines.

PS: I can't comment since I have <50 rep.
