I'm trying to use jUpgrade to migrate a Joomla 1.5.26 installation to 2.5.It is failing at:Upgrading progress...  Migrating undefinedIt never proceeds from here.Checking the error log in /administrator, I see:PHP Warning:  Module 'PDO' already loaded in Unknown on line 0  PHP Warning:  Module 'pdo_mysql' already loaded in Unknown on line 0
Joomla jUpgrade stops at Migrating undefined
