Hi,
I can see the debugger says that it doesn't find the OpenGraph tags at all on your headers.
However, if I look at the HTML of the page, I can see them.
Also, I can see that you have the URL
www.bellaidea.eu/catalogo
in the "canonical URL" setting of the product.
And I can see that the image it finds for your product is not an image found on the URL of the product, however, it is the first product image on the page
www.bellaidea.eu/catalogo
Also, the canonical URL is supposed to be the main URL you want to be indexed for your product. But here, you specified the main URL of the shop for this. I don't think it's a good idea to do that.
And I think that's why the debugger doesn't find the Open Graph tags as it's looking for them in the canonical URL, and not on the actual URL of the product.
So I would recommend fixing the canonical URL of your product, first and foremost.
Regarding the snippets, the plugin actually removes all the major ones like
{loadmodule} {loadposition} {slider} {tab} {modal} etc
I can see that you're using another type of content plugin which uses snippets with the format
which are indeed not taken into account by the plugin.
Which content plugin are you using there ?
