Hi Sheldon,

Thanks for the access. However to ensure the smoothness of our support workflow, kindly replied back to the original thread that you have created earlier so everyone can benefit from it.

Back to your issue, it seems like you have set the wrong url configuration for your facebook apps and that causing the issue when you try to autopost the post on your facebook. I've made some adjustment for your facebook apps and re-authenticate the apps and everything is working correctly now as it should. Please have a look.
