Django 1.6.4 debug-toolbar confusing error

[Florian Auer]

Hi

I am running 2 django 1.6.4 projects, both with debug toolbar enabled.

The first one ist a simple project, following the a cookbook tutorial and the toolbar works fine inside.
The second project ist the one, I'll wnated to start the real development in.

But there every call to the most panels give me a 500 error:
Internal Server Error: /__debug__/render_panel/

the main difference is with this project, that it has a template dependency, using a mysql connector instead of sqlite.
From my point of view I dont knwo whats the problem.

Any help is welcome

I have same problem. May it be related to urlconf?

[Martin Torre Castro]

I fixed it by following this 

http://django-debug-toolbar.readthedocs.org/en/1.2.2/installation.html

In my case, I had the wrong name in INSTALLED_APPS and I lacked this piece of code in urls:

if settings.DEBUG:
    import debug_toolbar
    urlpatterns += patterns('',
        url(r'^__debug__/', include(debug_toolbar.urls)),
    )

If anything similar happens to you, pay attention to the most little detail in the instructions.
