Adds support for embedding Facebook and Instagram posts in Block Editor (Gutenberg) and Classic Editor. This feature was removed in WordPress core due to deprecation of legacy APIs WordPress core used.
Prior to WordPress 5.5.1, WordPress had support to embed Instagram and Facebook photos, videos, notes, quizes, etc in posts created with Block Editor and Classic Editor. However, Facebook removed this legacy API in October 2020, and this plugin implements the new APIs to bring back support for Facebook and Instagram content embedding.
Note that you will need to register a Facebook developer account and create an app to get API credentials that this plugin uses. There is no coding necessary, but an API key needs to be created and set for the plugin.
Detailed setup instructions are available in <a href="https://php.watch/articles/wordpress-facebook-instagram-oembed" rel="nofollow ugc">oEmbed Plus guide at PHP.Watch</a>
