Had to do the domain verification from business manager. Wasn't happening with my id. Had to add someone else as facebook page admin and completed the steps from his facebook account. All good now.
After I used recommended settings from Social Rabit, my facebook account was disabled.
It's passed already about 3 days and I didn't received any news from them.
It was my main facebook account
If you are still in this problem even if your domain is verified with the steps above, click the Pages tab in the Business Settings, add a Facebook page in the next window. Go back to the Domains tab, click the Assign Pages tab in the right and and select that page you add. Go to Social Rabbit Facebook Poster, repeat the process and Test Post. The posts will be posted in the page you assigned in Business Manager, not in your main profile. You include this steps also mentioned above:+1. I am facing the same problem. And i did the same steps as shown in the first post. I even converted my FB page into business page and nothing.
Hope you fix it, guys.
