HTMLDOC Problem:

Htmldoc produced no pdf-output.
Commandline:
typo3conf/ext/htmldoc_linux/bin/htmldoc --datadir typo3conf/ext/htmldoc_linux/share/htmldoc -t pdf13  --webpage -f /var/www/vhosts/raffaltpersonal.at/httpdocs/typo3temp/hd_sKl0MZ - 2>/var/www/vhosts/raffaltpersonal.at/httpdocs/typo3temp/se_yLt8j9

This is the stderr output of the htmldoc command without the htmldoc_append parameters:
If you see no errors here please check your htmldoc_append parameters too.
typo3conf/ext/htmldoc_linux/bin/htmldoc: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

These are the first 80 chars of the output of the htmldoc command. Regularily this should begin with %PDF:

This is the html-data passed to htmldoc:
