FB tags generated ok but not recognized

This plugin seems to do its job on my site, e.g. on this page:

view-source:https://lebonheurestpossible.org/nutrition/

<meta property=”fb:app_id” content=”1109589345786857″/>
<meta property=”og:url” content=”https://lebonheurestpossible.org/nutrition/”/&gt;
<meta property=”og:title” content=”Nutrition : qui écouter ?”/>
<meta property=”og:site_name” content=”Le Bonheur est Possible”/>
<meta property=”og:description” content=”Toute prescription nutritionnelle est basée sur 20% de science et 80% de croyance (chiffres purement illustratifs)…”/>
<meta property=”og:type” content=”article”/>
<meta property=”og:image” content=”https://lebonheurestpossible.org/smiley-200/”/&gt;
<meta property=”og:image” content=”https://lebonheurestpossible.org/wp-content/uploads/2016/09/couple-eating.gif”/&gt;
<meta property=”og:image” content=”https://lebonheurestpossible.org/wp-content/uploads/2016/01/personalized-nutrition.jpg?w=300″/&gt;
<meta property=”og:image” content=”https://lebonheurestpossible.org/wp-content/uploads/2015/08/hqdefault1.jpg”/&gt;
<meta property=”og:locale” content=”fr_fr”/>

However, if I click the “share” button, I don’t get the proper picture, description, url.

FB debugger called on https://lebonheurestpossible.org/nutrition/ says:

og:url https://lebonheurestpossible.org/nutrition/
og:type website
og:title lebonheurestpossible.org
og:description
og:image

It means it is unable to harvest the FB tags. The Open Graph debugger says:

The ‘og:type’ property is required, but not present.
The ‘og:url’ property should be explicitly provided, even if a value can be inferred from other tags.
The ‘fb:app_id’ property should be explicitly provided

which is inconsistent with the existence of appropriate meta-tags.

What am I doing wrong?
