I am trying to create a copy of the built in blog app so I can customize
the fields in it. I have copied and renamed everything I can find in the
files. I can get the mediablog to open up in the admin screen to add a new
post. But when I click save, it saves it in the database and then gets the
following error.
Error during template rendering

> arguments '{'slug': 'test-mediablog-2'}' not found. 0 pattern(s) tried: []
I have looked at other threads with the same problems and I still cannot
figure out what is causing it. Here is the information that was asked for
in the other threads. I am changing the text color for the areas, I think
are involved.

I have the template "mediablog_post_detail.html" in the
/mediablog/tempates/mediablog/ folder and in the root directory
/templates/mediablog/ folder.
I have deleted all the url patterns above the one highlighted above and
still get the same error.
