 * After upgrading from 3.6.1 to 3.8.1 I am no longer able to access update-core.
   php, themes.php, and plugins.php. The only message I get is the “Not Found” I
   have tried everything from disabling all plugins and changing the theme back 
   to default via cPanel. I also tried a manual instal of 3.8.1 using a FTP client.
   Still no luck. Does anyone have a solution for this? Thank you for your time.

 * 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.
