Upgrade from 3.8.7 PL2 to PL3

[kyle1745]

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/showthread.php/408458-Vbulletin-3-8-7-pl3-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);

vBulletin 3.8.7 is not compatible with php 5.4 - you will need to ask your hosts to run php 5.3 instead.

There is not a way to get it working with 5.4? The site has been running fine on 5.4 for some time.
