Critical Errors That Must Be Fixed:

Bad Response Code URL returned a bad HTTP response code.
Warning

Errors That Must Be Fixed:

Missing Required Property The 'og:type' property is required, but not present.
Notice
Warnings That Should Be Fixed
Inferred Property The 'og:url' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The 'og:description' property should be explicitly provided, even if a value can be inferred from other tags.
Inferred Property The 'og:image' property should be explicitly provided, even if a value can be inferred from other tags.
og:image could not be downloaded or is too small og:image was not defined, could not be downloaded or was not big enough. Please define a chosen image using the og:image metatag, and use an image that's at least 200x200px and is accessible from Faceboo... See More
Parser Mismatched Metadata The parser's result for this metadata did not match the input metadata. Likely, this was caused by the data being ordered in an unexpected way, multiple values being given for a property only expecting a single value, or property values for a given property being mismatched. Here are the input properties that were not seen in the parsed result: 'og:locale:locale, og:type, og:title, og:site_name'

non capisco dove sia il problema

Sembra che Facebook abbia memorizzato nella sua cache informazioni errate, forzando il ricaricamento mediante il pulsante Fetch new scrape information sembra essere a posto.
