The "pt_sid=xxxxxxxxxxxxxxxxxxxxxxxx" at the end of every link in your knowledge base is caused by having the PHP setting use_trans_sid set to "Yes". To get rid of it, do one of the following:

1. Edit your server's php.ini file and set use_trans_sid to "No" or "0". On a shared host you probably will not have access to this file. This will turn off the feature on the entire server.
   
2. Edit the .htaccess file in the main directory of Lore and uncomment (remove the # in front of) this line:

          #php_value session.use_trans_sid 0

          Note: this will only work on Apache web servers.
