I downloaded the calaisphpdemo (OpenCalais_PHP_09Feb19) and run it on my linux server. After posting some text on the CalaisPHPDemo.html page, I was directed to the demo_results.php page with a "Unsupported Document" message. What is going on? I want to get the same results as I am getting on http://viewer.opencalais.com/ page.
I would appreciate for any help.
Thanks.
