Hello,

I have Phoca Open Graph Content Plugin on my site to generate open graph information for my blog articles.

However, this plugin is causing a conflict with TF learn.

By disabling Open Graph Plugin, the course page displays properly on TF learn.

However I need the Open Graph information, so I would like to enable the plugin. I am posting here because there was previously no problems with TF learn and Open Graph plugin.

Here is what happens when Open Graph Content Plugin is enabled:
