My client is on an old server running PHP 5.2.17, should I encourage him to upgrade to 5.3 or will it be ok?
Some weeks ago we had some issues with a PHP 5.4 installation, EE 1.12 and atomic repo (
some segmentation faults) and we stepped back to 5.3.
Update: The error was
Fatal error: Cannot override final method Mage_Core_Model_Abstract::clearInstance() in various PHP-Files
with PHP 5.4.17
