[Plugin: WordSocial] Works but with errors

With the latest version of wordsocial I don’t have an issue with the functions of the plugin. My posts show up on both my twitter and facebook pages respectively. However i get this error when I add a new post:

Warning: Invalid argument supplied for foreach() in ***/wp-content/plugins/wordsocial/inc/services/twitter.php on line 136

Warning: Cannot modify header information – headers already sent by (output started at ***/wp-content/plugins/wordsocial/inc/services/twitter.php:136) in ***/wp-includes/pluggable.php on line 934
