Thank you for the response, this new theme version didn’t help either.
I dug a little deeper in the matter and found the couse of the error.
tl;dr: Your theme with the custom-post-widget under 7.1 generates the error I have.
This plugin makes it possibel to input whole post-s into a widget. And when we user this combined with your themes, built in shortcode functionality it throws the mentioned error. As this a very unique combination of things I’m not requesting you to fix this, just wanted to tell you about it.
I think I will respolve this matter by looking for a another plugin or manualy enter the HTML code I want to display in my widget.
Anyway thanks for the super fast response and support!
