Warning: Declaration of description

Hello,

I have migrated a wordpress from one hosting to another, and I find an error in the new wordpress just migrated. I have found the file that presents problems, but I can not fix it. My knowledge about PHP is limited.

Error (Displayed on the new wordpress):

Warning: Declaration of description_walker::start_el(&$output, $item, $depth, $args) should be compatible with Walker_Nav_Menu::start_el(&$output, $item, $depth = 0, $args = Array, $id = 0) in /homepages/20/d762655672/htdocs/ar-t.es/wp-content/themes/kolos_en/admin/theme_functions.php on line 104

            $item_output .= $args->after;

            }
}

I have tried to modify this area of ​​the file, but the only thing I have achieved is to make the menu disappear (already reversed).

Thanks.
