see your admin screen

Appearance —>Menus

From that you could call up the pages or by custom’s

can you place the template code here ! ?

I’m sorry but you are using a commercial theme, you need to seek support from the theme’s vendors.

deactivate all the plugin and try the permalinks structure to default.
see your permalink structure is in post name change permalinks to

Default : http://www.trashprojects.de/?p=123

In admin panel
settings—->Permalinks—>Select default

Its this problem to be

#wrapper {
    overflow: visible;
    width: 100%;
}

In style.css line 12
replace
overflow:hidden ; to
overflow:visible ;
And its not the z-index prob

site url ???
