If you update your security settings on Twitter such as your email address or password, you will need to reconnect any related Twitter Services before Twitter allows the posts through as we will no longer have the correct details to enable this.
To resolve this, will need to update relevant Twitter services as follows:
1. Go to Services.
2. My Services.
3. Locate the Twitter account and then select the Edit icon.
4. Click 'Reconnect to Twitter'.
5. Provide the login details for that account.
6. Select 'Update Account'.
If this does not resolve the reconnection issue, please contact firstname.lastname@example.org.
