Hi,

The h.nav_link() function has been changed so that it no longer accepts the
c parameter.  If you change all occurences like

${h.nav_link(*c, *_('Home'), controller='home', action='index')}

to

${h.nav_link(_('Home'), controller='home', action='index')}

this will then work as expected we should update the example extension to
reflect this.
