SWISH Programs stop working after login

#1

Hi, I want to learn prolog on https://swish.swi-prolog.org/ but as soon as I login nearly all programs stop working and result in an error message. They work again, as soon as I log out. What am I missing? Many thanks, Carsten

Doesn’t ring a bell. What error? Can you provide a link to the specific program?

{"code":500, "message":"Arguments are not sufficiently instantiated"}
e.g. in the following example (in chrome).
The screenshot shows before and after login of the same code

Thanks. The detail is that you must login with Stackoverflow. With Google all works fine. I’ll see what is wrong.
