Hi and welcome.
Are you aware that your website doesn't work at all without javascript? It doesn't even show a message, just a black screen.
@LienRag you mean aurpera.onfabrik.com
Indeed.
Chrome is a security hole.
Try with Firefox+NoScript add-on...
@LienRag I'm kinda lost. I use duckduckgo and chrome usually and I haven't had any issues so far.
