For VKontakte, everything is great, you can transfer the title, description and pictures without any problems. Facebook worked exactly the same way just a couple of months ago, now using code

<a href="javascript:void(0)" onClick="window.open('https://share.yandex.net/go.xml?service=facebook&url=&title=&description=&image=','fb','width=190,height=280,resizable=no,menubar=no,toolbar=no,location=no,directories=no,status=no')" class="content-test__soc__item content-test__soc__item--fb">Поделиться</a> 

facebook server returns 404, what could be the problem? and how to fix?

I can’t use micromarking, because the url of the page is the same, and I need three different options.

    The address https://share.yandex.net/go.xml used in the first version of the Share block, currently not supported.

    Social networks periodically change their API to share, so often the links that functioned well earlier stop working.

    In your case, you can either directly use the Facebook API , or upgrade to the current version of the Share block.

    • In the case of facebook - only micromarking. - Roman Paradeev
