When adding script in post header, posts and post url not working on desktop

Took some figuring out where the issue was coming from but narrowed it down to this plugin.

You can check my test domain.

You can click the hello world post as it has not header script, if you click the test post on desktop it wont load, from the back-end when I click preview or the direct link, nothing happens.

However on my phone it does work.

Weird.
