Upgrade from 3.8.7 PL2 to PL3
 

I am receiving the following errors when trying to go to upgrade.php.
I have found this which I believe to be related:
https://www.vbulletin.com/forum/show...Install-errors

I am running PHP Version 5.4.10.

I made this change but still get the error:
In install/installcore.php find this line:

@ini_set('display_errors', true);

change it to:
//@ini_set('display_errors', true);
