I've seen errors like this when an url is missing a view to link to.
All urls defined must have a view aswell. Start checking there else
look the problem could be that you are missing args for a url tag in
your template. Some reverse matching need args to fill in the dynamic
part of the url, like the pk of an object. That would be where I would
start looking.
