{ $parts = explode( ‘?’, $src );

return $parts[0];


add_filter( ‘script_loader_src’, ‘_remove_script_version’, 15, 1 );

add_filter( ‘style_loader_src’, ‘_remove_script_version’, 15, 1 );

If you the right administrative privileges, you should be able to edit the file directly there. If not, you need to either use an FTP client or go to the cPanel and then “File Manager.”
