Cannot install Python Debug Toolbar

Hello

I get a 404. I followed the video 3 times, step by step.
It seems like an issue with the urls.
Has anybody installed this following the tutorial?

Okay I fixed it
I think the problem was the code itself was failing because of sessions not existing

I am having a similar issue even though I have Django.contrib.sessions in my installed app… can you help?

What error are you getting?
