Error when trying to connect

Hello

Just shopping around for forum solutions that integrate with wordpress, and thought I’d try phpBB again when I saw your plugin.

I’ve successfully installed phpBB, and automod. Went through successfully the process of setting up automod, but when I go to connect via the plugin, I get the following error:

Fatal error: Cannot redeclare make_clickable() (previously declared in /home/??/public_html/dev/wp-includes/formatting.php:1573) in /home/??/public_html/dev/forum/includes/functions_content.php on line 679

Thanks. Gavin.
