I have successfully installed Autotweet free version on my joomla 2.5 site. But trying to set up a facebook account becomes a problem. While from admin backend , setting up Facebook Accounts - Add Account , i clicked "Authorize application and grant permission" and was taken to the 1st movers facebook page where i got the user id and access token displayed.i copied and pasted both the user id and access token on the autotweet facebook account data set up box at the joomla admin backend.. But after saving the user id and the access token in the account data set up of autotweetNG i got the error message
"OAuthException: Malformed access token " showing next to my facebook account id.
