Reply To: Problem after update – where to get old version?

This is happening because of the image you have added into the menu item.

Try replacing your CSS for that image with this:

.main-navigation .bild-ls {
    padding-right: 2px;
    display: inline-block;
    margin: auto;
    vertical-align: middle;
    width: 30px;
    height: 30px;
}

Yes, try deactivating that plugin. There may be a compatibility issue I need to look at (never heard of it before now).
