Hi,
I have some additional info that might help analyzing the problem. After
searching the internet I found a similar problem on this site:
http://www.mediawiki.org/wiki/Extension_talk:Collection/Archive_1#Book_has_0_Bytes
I applied the patches indicated there, since my version of php is 5.2.17.
1. the array problem:

This morning I added two lines of debugging code to the beginning of
localsettings.php, as indicated here:
http://www.mediawiki.org/wiki/Manual:How_to_debug
error_reporting( E_ALL );ini_set( 'display_errors', 1 );
I tried again to download a page of my wiki as a PDF and I was able to
download collection.pdf, which contained the following lines:
<br />
<b>Warning</b>: readfile() [<a
href='function.readfile'>function.readfile</a>]: Filename cannot be empty
in
<b>/is/htdocs/wp1045034_DIC9D7OW2C/www/frankfurt.vij.de/wikijusta/extensions/Collection/Collection.body.php</b>
on line <b>1127</b><br />
The warning refers to the line of patch that I inserted into
Collection.body.php:
+ readfile( $tmpfname );
This suggests to me that somehow the pdf doesn't get filled on the
pediapress server.
What do you think?
