So I upgraded to 4.2 without a glitch, accept when I attempted to change styles from Minimalist Green to Professional Blue, then when I published the site the home page went blank. However, if I change it to index.html (via FTP) it works fine.

Why can't I see my main page when it's saved as index.php? but I can see it if it's saved as index.html

Btw: this site (www.intellectualsecurity.com) worked fine with index.php for the past 4 years.

Thanks,

Aaron
