Pohmeliy Scripts FB Script Error

I am using Pohmeliy's FB script for posting to groups. It has been working for me until today. When I run the script to post to groups, the log shows it's posting to the group ok, but it errors at the group activity page logging it as an error. When I check my account, the post has been posted to the group, however. Further checking this error, on FB activity log (my history), I do not see the post on my activity log.

Is this a script error or it's a FB error. I can run the script, but the problem is that the script treats this error as non posted and proceed to the next group without a delay pause. This, in turns, will cause my acc in a temp ban for going to fast.
