As in the title,
in my website (http://www.mauriziozani.it) the menu (top page) is showing not properly the arrows for the sub-menu in some cases; I mean:
- for HOME, an arrow is present, but no sub-menu is setted
- for APPUNTI, no arrows are present, but I've setted (as you can see hovering the label APPUNTI) several sub-menus
and similar cases.

This situation seems present (but I'm not so sure) when I've updated WordPress to version 4.4...

did you check the forum for a patch? (hint-hint)

Yes, but before changing the code I wanna know if is a "system problem": in this case everyone has Atahualpa 3.7.22 & WordPress 4.4 (with the same relative versions as myself) must present the same problem, 'cause I haven't done any modification.

This happens to someone else?

Did you read the patch thread?

Great! Thx, it works
