IFrame not working

[k0nsl]

Hello @TylerLH,

I came across your project because I was looking for something similar to what you are offering. I decided to give it a try.

I can indeed view it perfectly fine when entering the URL, e.g:
http://gh-widget.plugins.k0nsl.org/?username=k0nsl&repo=spammer-kartotek&limit=10

That is working just fine. However, if I include it as an IFrame on a external site such as this one then it doesn't work:
https://spamdb.k0nsl.org/page/k0nsl

Any ideas as to what I am doing wrong here?
