How to fix "Something Went Wrong!" error on Wordpress

I'm getting an error with the mobil version of my webpage. There is no problem when accessing the website through a computer or laptop but when accessing it on a mobile device it says something went wrong.

Just to give you an idea of the setup - I'm designing the website through Kartra - and using WordPress as the website builder.

Can someone please help I've also attached a screenshot of the error I'm seeing on the phone.
