Thank you for your question.
Please share your store URL, page URL and also password (if your store has one), I'll help you out to the best of my ability.
Sorry Diego, I didn't realize I could send a preview link. This is a fresh install of Testament. This page has 8 photos and 1 video. Video plays fine, but doesn't show up in fancybox.
Contacted theme developer support (We are Underground ) and they said "fancbox is not supposed to work with the video, and it's something we can't enable", yet fancybox web site says otherwise...
Thanks for the URL, I just checked it.
In case you're unfamiliar with these technologies you'll likely want to hire a Shopify developer to assist you.
I have that.
"I'm afraid that unfortunately there is no simple copy-paste solution..."
This is the Technical Q&A section, right? That's exactly what these forums are for. That's why I'm here. If someone else has done it, there most certainly is a simple copy-paste solution. Or, if someone else ISN'T having the same issue, they would state it and it would help me to determine if it's simply an error on my end.
Thanks for weighing in and giving your opinion. Have a great day.
