    Try re-uploading all files & folders - except the wp-content folder - from a fresh download of WordPress. Make sure that you delete the old copies of files & folder before uploading the new ones.

    eAccelerator and suPHP don't play nice together because of file permissions

    Disable eAccelerator ...rebuild Apache

    or try

    Adding this to .htaccess

    php_flag eaccelerator.enable 0
    php_flag eaccelerator.optimizer 0

    Boo! Just upgraded one of my sites to 3.6 (and i'm a ROOOOKIE when it comes to hosting)then tried to load Ultimate Construction Page plugin and got the fatal error.

    What the heck is eAccelerator and suPHP? Where do I find them in cPanel?

    Sorry to be such a noob, but, you know how it goes!

    Even uninstalling complete WP from cPanel for the affected site and reinstalling 3.5 didn't work. Hm.
