I figured it out! This was posted by questions4wp about a problem he was having in WP 3.7 which is the same problem I was having. This is what he found…
“I use InMotionHosting, but the solution might be relevant for others. WordPress 3.7 requires PHP version 5.3. The cPanel on my host shows that it is indeed running a 5.3.* release, so I didn’t think anything of it. It turns out that there are multiple versions available for different applications. To force that domain to use PHP 5.3, the tech person added the following line to the top of my .htaccess file:
AddHandler application/x-httpd-php5 .php”
I use web hosting hub but it was the same problem. I added the code to my .htaccess file and sure enough it worked! Hopefully this helps out someone else as well.
