SyntaxError at line: 1, character: 1; Unexpected: "" #35

Closed gsingh93 closed 3 years ago

gsingh93 commented 3 years ago

I see 'SyntaxError at line: 1, character: 1; Unexpected: ""' in a red box when I navigate to this study: https://listudy.org/en/studies/3xdxc5-english-symmetrical-four-knights-master.

The console shows two messages:
