Boldial v2.4 with WordPress v4.6.1

Hello, my name is Jean-Claude,

We finally opted for the purchase of the theme Boldial v2.4.
Our site was updated with this version. Items already created in the portfolio
are reappeared in the display(posting). However, when I want to modify an
item of the portfolio, the application seems to turn in the space.
He(it) never posts(shows) the contents of the item.
I thought that the purchase of the theme Boldial v2.4 would solve the problem of
the portfolio in her(it) v4.6.1 of WordPrerss, but at present, it is not the case.
What do we have to make to remedy this problem?

Thank you for your collaboration.
Good day.
