Hi Diederick,

deba is a function declared in class.tx_jwcalendar_pi1_library.php (see 
http://tinyurl.com/5ped2)

   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.

HTH,
Rainer
