Blog and articles entries redirect to homepage

[Damer]

Hi, something is broken in our forum but we can't figure out what. Every time we create new blog post or add a new article every link replaces "blog" in the URL with # so and it redirects it to the homepage. It worked fine at first but after a couple of hours of testing first the article section got affected and then the blog. Now we can't post in either.

EDIT:
nevermind, we figured a way around it by adding a subcategory.
