The error details say ‘Fail message – An unknown error occurred. Please sign in to Facebook and try your upload again.’ Well, I’m logged into facebook on my app and the website. I’ve tried logging out, and logging in. I have also tried powering my phone off, and on. I have even tried deleting the app, and re-installing and a combination of the all. Why won’t my Android on AT&T load pictures to facebook? How can I fix it? Please help. Thanks.
