Hi guys,
I would like to get this marvellous application up and running on my site. Installation was OK. I changed the session.php file as recommended. When I try to go to the login page I get the message:
Fatal error: Call to undefined function: pnthemeload() in /home/opensite/public_html/PhpMyLibrary/polerio/module/lib/content.php on line 45
Anyone knows what could be the problem?
