Scenario: You go to your Twitter profile page and attempt to connect your Facebook account, and no matter what you do all you see is There was a Twitter server error. The error has been reported to our engineering team. Please try again as it might be a temporary problem.

Solution:

• Log in to Twitter and verify that Facebook is disconnected.
• Log out of both Facebook and Twitter.
• Clear all of your Facebook and Twitter cookies.
• Close your browser.
• Launch your browser and log in to both Facebook and Twitter.

Now try to connect Facebook to your twitter profile again. It should work this time.
