Broken links in navbar #27
Description
The links in the top-right navbar are wrong when accessed from a custom page. For instance, if I add a page test.md and try to access the contact page then I'm redirected to https://mysite.github.io/test/contact instead of https://mysite.github.io/contact.
I suspect that the bug comes from this line but I didn't figure out how to fix it.
This is somewhat related to issue #20.
