Question

I installed PublishContrib and it works find in producing HTML files and also to produce a zip file with them. But when I try to produce a PDF, I get the following error in the Browers (at the end of the page after the "[topic name]: published" messages):

Content-type: text/plain TWiki detected an internal error - please check your TWiki logs and webserver logs for more information. Can't use string ("TWiki::Contrib::PublishContrib::") as a HASH ref while "strict refs" in use

In the apache-logfiles/error.log I see the following:

I use the TWikiVMDebianStable installation as the basis for TWiki. I insatlled HTMLDoc and it works fine from the prompt.

Is there an error in the PublishContrib or did I something wrong in the config?

Here the lines in LocalSite.cfg:

$TWiki::cfg{PublishContrib}{Dir} = "/home/httpd/twiki/export/";
$TWiki::cfg{PublishContrib}{URL} = "http://twiki-vm/twiki/export";
$TWiki::cfg{PublishContrib}{PDFCmd} = 'htmldoc --webpage --links --linkstyle plain --outfile %FILE|F% %EXTRAS|U% %FILES|F%';

Same initial error message as in Bugs:Item3515, not sure though if the same bug.

Hi Peter. I installed the changes from Crawford but I still get the same error. It seems, that the change fixes a security problem but not the initial error.

The problem is fixed with the version from Feb 10th 2007. After installing the latest version, the problem did not occure any more.
