In the fight against spam over the weekend, something horrible went wrong with new code in the tweet posting script. In some cases it duplicated scheduled recurring tweets. Go figure. Fix one thing and break another.
All recurring tweets that appear to be duplicates have been placed in the red error condition for you to review.
You can either bulk delete them with the Tweets, Delete function in the top menus, or, if it is a valid recurring tweet, you can simply edit and reschedule it.
There should be one non-red recurring (and still active) tweet, of which all the red ones are duplicates.
You may also find that some of your Ping.fm recurring tweets have been advanced several recurs into the future. Unfortunately we cannot fix that by means of a script. We ask that you edit those recurring tweets and reset the scheduled date and time to what it is supposed to be.
Apologies for the inconvenience.
