"Uncaught SyntaxError: Unexpected token < " in first line

I know this question has been asked many times but I can't find a solution for my problem.

On my local machine everything is good, but when i upload files to the server (000webhost), i have six errors, and descripton of these errors is "Uncaught SyntaxError: Unexpected token <".

Thanks in advance.
