Category Website Bug

Hi,
I’d like to notice a bug. I create category Blog in the menù Setup->Website->Blog Category
If the name of category contain a space, the link from the site not work.

I think that the problem is the lack of special charachters in the creation of the link.

The link generated when i click on Categoria A link in the blog section, is:

http://localhost/None

instead of

http://localhost/blog/categoria-a

The result is an error page.

Regards
Alessandro

This is pretty strange:
We have a lot of spaces in our categories

https://blog.frappe.io/blog

Either ways, we have dropped the sidebar in version 5 keeping in line with the modern, minimal, web friendly layouts.
