Setup message

I get following message when I call setup.

“Fatal error: Declaration of Ai1ec_Html_Setting_Select::render($output = ”) must be compatible with Ai1ec_Html_Element_Settings::render($output = ”, $wrap = true, $hidden = false) in /home/.sites/478/site9759627/web/wp-content/plugins/all-in-one-event-calendar/lib/html/element/setting/select.php on line 12″

Please help.

Best regards

Siegfried
