Unwanted blog code loading on sub page

Hi Pulse Team
I have the same issue as in this topic: Blog code loading on sub page
But it wasn’t resolved there. How did you fix this?

So for short: there is code loading on every post inside my blog. It just appeared recently, but I don’t what I did to make it appear that way. It wasn’t a problem this morning when I was working on the site, but now it is, and it is everywhere (I also have sub blogs).

See: energy-therapy.be/nl/overzicht - this is a test site though.
