error 404 on facebook share from second store view
I have a problem when sharing products on Facebook from a second store view, with different url, to be more clear:
Store 1 in English: url of the product X (default store view in English) /product_in_english.html (I got only one error of og: image (width and height) but it is correctly shared in FB)
Store 2 in Bulgarian: product url X (store view bulgarian) /product_in_bulgarian.html (404 error in FB.) The following mandatory properties are missing: og: url, og: type, og: title, og: image, og: description, fb: app_id)
This results come from the debugger of the FB developers console errors.
The strange thing is that if I open the inspector in the browser I have all those mandatory properties mentioned. (see screenshots)
Any idea why I get the error? Or some orientation what I have to look for to fix it?
