Links on tags page not working

[KonradUdoHannes]

On the blog the tags list the tagged posts correctly, but the hyperlinks to the individual posts are broken.

The link to the tags page is https://codes.correlaid.org/categories/

Interestingly the tag links work in the forked version of the blog created in relation to #14

For the forked blog the url and base_url settings where undone, which suggests that the problem of the broken links lies with them.
