www.micropdr.com/negozio zencart.1.5.1 when I share on facebook or whatsapp I don't see image miniature but only link

I need help fixing my website's code on www.micropdr.com/negozio zencart.1.5.1. Currently, when I share on Facebook or WhatsApp, only the link appears and not the image. I have added Open Graph tags to my website's code. I am looking for someone who can help me troubleshoot this issue and ensure that relevant images appear when sharing on Facebook or WhatsApp. The ideal candidate should have experience with Zencart, Open Graph tags, and social media sharing. The issue only affects Facebook and WhatsApp, and I haven't tested other platforms.
