Navigation problem – Search and Login not right aligned

The alignment of the login and the search isn’t correct.
Normally it should be on the right side, but on my site it is directly next to the “Contact” navigation point.
This was before i changed something in the css.
(Only deleted the +, if there is a submenu CSS: content: “”; to content: “”;)
So this shouldnt be the problem. This problem was there since the beginning.
Maybe someone of you can help me with this little problem.
