Product not display please help

I have the same issue. I have not done the WP 4.5 update.
Everything was working well before, but not anymore. When I click on the product itself it is not visible. https://direct-internet-printing.de/produkt/celebration/

“Nothing was found at this location. Try searching, or check out the links below.”

Thanks a lot for your help

Although it is defined twice; could be the sharing plugin at fault.

I deactivated all plug ins, but the problem is still there.
