I also did an update, but the portfolio object works for me, both when working on a portfolio object that existed before the update and on a newly added portfolio object, see my two test pages

Test page with old portfolio >> https://findelinks.de/123shop-hosteurope/portfolio.html

Test page with new portfolio >> https://findelinks.de/123shop-hosteurope/seite-789.html

Hello Serhii,
I am sorry about the issue.
Could you provide additional details on the error? Is there a page online containing the Portfolio objects which I could check?

Eric

I downloaded it again. And everything started working. Something went wrong with the first update. Thank you!
