Share Post button disapeared

Hi HB Team,

It seems that the Share Post button disapeared from the portfolio single page since the last update.
Even if the function is active in the Portfolio Settings of Highend options, it is not diplayed on the porfolio pages.
Example : https://info.welcomee.com/portfolio/photos-messenger-interieur/

How can I get back this Share Post button ?

Thanks for your help.
