Bug when trying to save sidebar

Hello

When trying to save a sidebar I am recieving the following error N.B the asterix are just to prevent my website name being disclosed.

Warning: Invalid argument supplied for foreach() in /home/*****/public_html/wp-content/plugins/content-aware-sidebars/admin/sidebar-edit.php on line 791

Warning: Cannot modify header information – headers already sent by (output started at /home/*****/public_html/wp-content/plugins/content-aware-sidebars/admin/sidebar-edit.php:791) in /home/*****/public_html/wp-includes/pluggable.php on line 1174

This does not relate to the previous issue I reported with Tabs Responsive as I have already tried disabling that plugin to see if was another conflict. I have recently updated to version 3.3.1 of the Content Aware Sidebars plugin

Any ideas
