Guzzle Fatal Error – MUST READ

Facebook API uses a recent version of the Guzzle library. Other plugins may use an older version of Guzzle. When this happens, there is a chance to see fatal errors.

We did our best to fix potential problems on our end, but it’s still possible to have conflicts.

If this is the case, use our contact form to send us details. We need the error message and, if possible, the plugin name that causes the conflict.

It’s also a good idea to contact the other plugin’s support and let them know about the Guzzle issue. Ideally, they should be able to update to the latest version to avoid this problem.
