PHPbb3 link double slash and wrong URL

Hello help
I am using Zen Cart 1.3.9b and my website is nilandsplace.com/radio
I am trying to figure out this problem for two stores. When I have the correct path for PHPBB set in my configure file I get a link like this> nilandsplace.com/radio//help/radioforum/index.php and this result The requested URL /radio//help/radioforum/index.php does not exist. this is right because it lives at > help.nilandsplace.com/radioforumthe configure fill reads like thisdefine('DIR_WS_PHPBB', '/home6/nilandsp/public_html/help/radioforum/'); and this is the only way it will let the fourm links show up. I have tried the code from DrByte for the "class.phpbb.php" , but this did not fix anything. Why is the link showing the root link for /radio/ at all? If I use any thing other than```
define('DIR_WS_PHPBB', '/home6/nilandsp/public_html/help/radioforum/');

Thanks
