white schreen

The JFBCContent plugin and the Open Graph - Content plugin are separate. Neither requires the other to be enabled.

When you get the white screen, what page are you looking at? Is it the front-end, or admin area? Is it the whole site, or just specific component type pages that cause it? Can you go to the Joomla Global Configuration and set Error Reporting to 'maximum'? That should show an error on the white-screen page that will let us narrow down where the problem lies. Let us know that error, and we can help you get things going.

If you disable the Open Graph - Content plugin, you won't be able to create Content objects using the plugin.

Thanks,

When do you see those different errors? Can you let me know when you get the white screen, what page are you looking at? Is it the front-end, or admin area? Is it the whole site, or just specific component type pages that cause it?

We're looking into another report of the first error message you posted, but still need to determine what configuration is causing it. We've never heard of the 2nd. Please let us know what type of page(s) you're viewing to see those errors.

Thanks,
Alex
