The call to print_notice() has too many arguments starting with 'Provided URL is a HTML ...e dropdown menu below.'. ( Ignorable by Annotation )

If this is a false-positive, you can also ignore this issue in your code via the ignore-call  annotation

        /** @scrutinizer ignore-call */ 
675
        print_notice("Provided URL is a HTML page referencing multiple feeds, please select required feed from the dropdown menu below.");

This check compares calls to functions or methods with their respective definitions. If the call has more arguments than are defined, it raises an issue.

If a function is defined several times with a different number of parameters, the check may pick up the wrong definition and report false positives. One codebase where this has been known to happen is Wordpress. Please note the @ignore annotation hint above.
