Unknown warning show in my WP theme

Hi,
Recently I have submitted a new WP theme in ThemeForest. But there are showing some unknown warning. Those errors don’t show in my theme-checker.

My question is what are those warning and which plugin they are using for theme check.

Thanks

Themeforest sent me this warning.

It sounds like your functions.php file have whitespace before <?php or after ?> it’s also better to remove ?> from the end of your files

The reviewer sent you a PHP error and your screenshot was themecheck plugin’s error. Try to enable your WP_DEBUG.

Thanks

Perfect solution.
