I created this WordPress/Fizz theme/Woocommerce shop: http://jexiste.clothing/ Now I'd like to share it on Facebook and on other social networks but the Open Graph is a total mess: https://developers.facebook.com/tools/debug/sharing/?q=http%3A%2F%2Fjexiste.clothing%2F I tried fixing it with Yoast SEO and other plugins but there's always a problem. So I deactived and deleted all the SEO-related plugins. I added the info in the head section of the Fizz theme's header.php using the WordPress dashboard editor but it won't help.
I'd like to force Facebook using this image when publishing the main page ( http://jexiste.clothing/): http://jexiste.clothing/wp-content/uploads/2017/12/fb.jpg. I want Facebook to use the article's photo when publishing an article page (http://jexiste.clothing/product/hologram-sticker-pack/ for example). The description should be the same as the published page's one.
What should I do? I tried everything. There must be a code somewhere I can edit or so...
Thank you in advance and happy 2018 to you all!
