In this case I'd double check if evey *.php files in your pmwiki  
installation, especially the ones in the local and cookbook directories:
1. start with "<?php" as the very first thing on the very first line  
(without the quotes)

2. omit (don't have) "?>" on the very last line: they should NOT have it

3. if you have created or edited some files yourself, make sure your text  
editor does NOT save the files with "Byte order mark" (or mask): these are 3  
invisible bytes at the start of the file, they are not needed and sometimes  
break PHP scripts, especially regarding headers, like in MIME declarations.
