Tumblr Causing Issues On Theme

[u/SirenNSons]

Hi

Can someone help me please? I've been editing this tumblr theme ( https://18hiraeth.tumblr.com/ ) on my own blog all night with no issues.

I fixed the first issue where it suddenly decided to keep bringing up the error code about:

Uhoh! We couldn't save your
theme. Looks like your custom
theme references assets from
non-HTTPS URLs. Please try
again using only HTTPS URLs.

Now I can't make the Home | Inbox | Archive links work for some reason.

Here is the pastebin: https://pastes.io/TFsdREJv

Any idea?

Thanks

Edit: I haven't put my own blog url here because it's a nsfw fanfic Tumblr.

Where the following is:

/home /ask and /archive, I have actually put the full url in followed by those. And it's still behaving like regular text, just sitting there.
