What functionality are you trying to get from the integration? I thought whmcs was a hosting config system while wordpress is content management.
i want make a hosting company. WHCMS is management but the front page from website i want use wordpress
I get that but why do they have to be integrated. I don't see any reason why whcms would need to send info to WordPress or vice versa
has already been done. See: http://forum.whmcs.com/showthread.php?t=10658&highlight=wordpress will let you know exactly how to do it. They have a lot of free mods listed on their forums as well as many premium paid mods TJ
