Gigantic Gap between menus and posts

[ghost]

Hi, I have a very strange problem, which is probably a user configuration issue
However, there's a gigantic gap between my Menu and my Posts

The Site is already live at: https://blog.tinfoil-hat.net
the source is available at: https://git.tinfoil-hat.net/tinfoil-hat/tinfoil-hat.net

it looks something like this:

Okay, I found the Problematic Code which caused this behaviour:

      <div class="site-nav-right">
        <div class="social-links">
                    {{ if .Site.Params.githubName }}<a class="social-link" href="https://github.com/{{ .Site.Params.githubName }}" target="_blank" rel="noopener"><svg xmlns="http://www.w3.org/2000/svg" viewBox="0 0 24 24"><path d="M12 .297c-6.63 0-12 5.373-12 12 0 5.303 3.438 9.8 8.205 11.385.6.113.82-.258.82-.577 0-.285-.01-1.04-.015-2.04-3.338.724-4.042-1.61-4.042-1.61C4.422 18.07 3.633 17.7 3.633 17.7c-1.087-.744.084-.729.084-.729 1.205.084 1.838 1.236 1.838 1.236 1.07 1.835 2.809 1.305 3.495.998.108-.776.417-1.305.76-1.605-2.665-.3-5.466-1.332-5.466-5.93 0-1.31.465-2.38 1.235-3.22-.135-.303-.54-1.523.105-3.176 0 0 1.005-.322 3.3 1.23.96-.267 1.98-.399 3-.405 1.02.006 2.04.138 3 .405 2.28-1.552 3.285-1.23 3.285-1.23.645 1.653.24 2.873.12 3.176.765.84 1.23 1.91 1.23 3.22 0 4.61-2.805 5.625-5.475 5.92.42.36.81 1.096.81 2.22 0 1.606-.015 2.896-.015 3.286 0 .315.21.69.825.57C20.565 22.092 24 17.592 24 12.297c0-6.627-5.373-12-12-12"/></svg></a>{{end}}

                    {{ range .AlternativeOutputFormats -}}
                           {{ printf `<link rel="%s" type="%s" href="%s" title="%s" />` .Rel .MediaType.Type .Permalink $.Site.Title | safeHTML }}
                    {{ end -}}

        </div>  
        {{ if .Site.Params.RSSLink}}
        <a class="subscribe-button" href="{{.Site.Params.RSSLink }}">Subscribe</a> </div>
        {{else if .Site.Params.showSubscribe}}
        <a class="subscribe-button" href="{{if .IsNode}}{{.RSSLink}}{{else}}{{"rss/index.xml" | absURL}}{{end}}">Subscribe</a>
        {{end}}    
      </div>

When removing the lines:

        {{ if .Site.Params.RSSLink}}
        <a class="subscribe-button" href="{{.Site.Params.RSSLink }}">Subscribe</a> </div>
        {{else if .Site.Params.showSubscribe}}
        <a class="subscribe-button" href="{{if .IsNode}}{{.RSSLink}}{{else}}{{"rss/index.xml" | absURL}}{{end}}">Subscribe</a>
        {{end}} 

the site renders as expected. But that means I can't insert my RSS Feed Subscribe Button in Header ...

Closing now since Gigantic Gap dissapeared
