Hello, thanks for your quick reply.
Since my time schedule for constructing the blog is tight, I rolled back to version 1.4 and this temporarily resolved my problems.
I will as soon as possible try to locally duplicate the installation, check it further and, in case of issues, get back to you with screenshots or possibly a small video capture of mine trying to customize pages order and parenthood, since “my” problem doesn’t affect the theme’s look and feel but only those menu-bar options.
Kind regards
