Open Source Document Management System | OpenKM

Hi all

I'm using Open KM version 5.1.9 on ubuntu 10.04. I'm not able to preview the PDF files . Getting the error "There was a problem with Conversion Generation . Please Contact your Open KM Administrator ." I have attached the server log. I have installed pdf2swf software . And i'm getting preview unavailable for other files such as txt files , jpeg files , MS word extra... Could any one please suggest.

Thank you

Take a look at http://wiki.openkm.com/index.php/Migrat ... 8_to_5.1.9 if you pdf2swf parameters is correct.
pdf2swf is executing correctly from your terminal ?
