While following a tutorial from "Coding For Everybody - Learn wagtail", i ran into a problem while messing with the Routable Pages video, which i copypasted the code found at his GitHub into my Blog and now the following error appears:

I've tried to redo all the steps, watched the video over and over but nothing worked.
CodePudding user response：
In the line
{% routablepageurl page " latest_posts" %}
you have a leading space before latest_posts - you should remove this.
CodePudding user response：
The error message itself indicate that the url namespace you are looking for does not exist ' latest_posts'
Look here :-
Reverse for ' latest_posts' not found. ' latest_posts' is not a valid view function or pattern name.
So if you check in your urls.py file you will find the correct namespace, that you can use at that place.
As of now the issue is in the My blog_listing_page.html file.
