[Plugin: Another WordPress Classifieds Plugin] Missing Argument?

I am getting this warning in my error log? Not sure how to resolve it. Other than bullets showing up on the Classifieds page, for each category, everything seems to be working fine with AWCP.

PHP Warning: Missing argument 1 for awpcp_admin_sidebar(), called in …/public_html/wp-content/plugins/another-wordpress-classifieds-plugin/awpcp.php on line 2688 and defined in /home6/bluegrd9/public_html/wp-content/plugins/another-wordpress-classifieds-plugin/functions_awpcp.php on line 2933
