wp-open-graph

Plugin make a lot of problem then be useful.. I uninstall it from all my sites....

It works, when configured correctly 🙂 Don't forget to add a default image URL in all three URL fields. I forgot the first one and nothing happened for posts/pages (it would only insert OG image information for the main page).

This plugin ads his own content to the html tag attributes. Unfortunately it replaces them instead of filtering (appending new ones). The lang attribute which is critical to SEO gets striped out which poses a huge SEO problem for the site using this plugin.

Has been working fine for me for several years, even though not updated. It's a simple plugin.

Plugin works, also the plugin is over 2 years not updated. Really great.
