CiviCRM Community Forums (archive)

Long story short I attempted an upgrade from CiviCRM 4.1.2 to CiviCRM 4.2.7 not realizing until after I clicked upgrade that our web sever is still running MySQL 5.0.95 and not 5.1, when trigger support starts.  I realize this was the core breakdown. After restoring Drupal 6 + CiviCRM site files + sql databases, I attempted to bring the site back up but kept getting an ISE 500. Looking at the PHP error log I discovered:

[04-Feb-2013 16:06:06 America/Phoenix] PHP Fatal error:  Call to protected CRM_Core_ClassLoader::__construct() from invalid context in /var/www/virtual/<site_name_omitted>/sites/all/modules/civicrm/drupal/civicrm.module on line 225

Tracing to line 225 in civicrm.module I commented out the following lines: 225 and 226 and sure enough the site loaded again. After researching the error a bit more, I ran into the following: http://issues.civicrm.org/jira/browse/CRM-10532 which prompted me to revise the snipped below. 

My question is, are we going to have any problems down the road using CiviCRM with the following modifications?  Is there anything else we can do here?  Eventually we need to upgrade to Drupal7 and CiviCRM 4.2.x and this is planned, but will take time and want to avoid having core issues between now and then. 

Thank you in advance for any advice provided.
