Need restart and add blog as CMS application for work

[mradochonski]

@viatoriche I have djangocms_blog in installed apps and still getting the same error. Unless you ment something else.

[christianwgd]

I had the same Problem. Adding the blog application to the page helped in some cases, but then i couldn't use the blog as a placeholder in my other templates (without assigning the page to the blog app). I ended up adding the following line to my urls.py: url(r'djangocms_blog/', include('djangocms_blog.urls', namespace='djangocms_blog')), Maybe it would be a good idea to add this to the configuration docs or maybe i'm completely wrong?

[yakky]

The correct process to attach the blog to the urlconf is documented in the last step of the Quick Hint: https://github.com/nephila/djangocms-blog#quick-hint Using the apphok it's by far the recommended method to use any djangocms-enabled application
