{SCOpenGraph} broke in 6.0.1 update

The only requirements for the tags to be properly stripped and replaced is that you have the JFBCSystem plugin enabled. If you have a caching extension or the System - Cache plugin enabled, those plugins should be ordered after/higher number than the JFBCSystem plugin.

There's not really any other requirements to get things going.

Beyond the {SCOpenGraph ..} tags, are any other tags showing for things like the login or Like/share buttons?

Thanks,

The "Admin Render Key" setting can be found in the Social -> Misc tab. Check your setting there. If set, the key should be required for any tags you add on the page. If you're seeing odd behavior where the key is, or isn't, required in some cases, let us know, and we'll gladly investigate.

Thanks,
Alex
