WP 3.2.1 (Multisite)
I use the section widget plugin to manage sidebar jQuery UI tabs.
I see the following error above each instance of the section widget in the sidebar, when logged in as Admin and FEE is active,
Warning: Missing argument 2 for FEE_Field_Widget_Text::wrap() in /.../.../public_html/wp-content/plugins/front-end-editor/php/fields/widget.php on line 101
here is a screen cap if it helps: http://goo.gl/vUwSq
if you would like me to test this out or give you admin rights to debug - just let me know.
