PHP won't parse under https, but will with http

I'm not sure if this is the right forum for this question, but I'm hoping someone can help nonetheless. :) I installed an SSL Cert. on a site the other day for a checkout page, and the php won't parse. If I take the "s" off, it parses just fine. I have a feeling it's an httpd.conf setting, but I don't know where to look. Maybe it's a php.ini issue to make it parse on port (whatever SSL is)? Thanks for any suggestions. -jason ------------------------------ web developer Factory7.com 354-9977
