I have a Web site to which I've added WordPress. But, since I wanted a more comprehensive, informative home page, I decided not to use WordPress's index.php as my home page. Instead, I merely linked WordPress by giving index.php a new name, blog.php.
Natch, the change in name has screwed up everything so visitors can't comment, etc. I expect I'll have to go into several files and rewrite some code but don't know where to begin. Thanks for your help.
