Hi Diederick,

deba is a function declared in class.tx_jwcalendar_pi1_library.php (see 

   function debA($a){
         foreach($a as $w => $s)
             echo "$w => ".$s.' <br>'; //['uid']

It seems not to be part of a class, so if you copied the file to a new 
extension, this function is double declared - this causes the error.
