 * This plugin is working fine on the live version of a certain site of mine, but
   on the local version (which I am running in debug mode) I am getting this error:
 *  Strict Standards: Declaration of aec_contributor_list::form() should be compatible
   with WP_Widget::form($instance) in /Applications/MAMP/htdocs/empsolutions/wp-
   content/plugins/ajax-event-calendar/inc/widget-contributors.php on line 64
 * Searching for the first few words of this error message brings up a whole whack
   of other sites that are generating the same error, and probably don’t even realize
   it. I’m not sure how to correct the error here, and since it appears to be some
   kind of issue with following WordPress standards it really seems like something
   the developer should take care of.
