I have installed Civi 4.2.19 in Joomla 2.5, to upgrade the 4.1.1 version. I cleared all cache and then tried to run the database update. I got this fatal error:
Fatal error: require_once(): Failed opening required 'CRM/Upgrade/Incremental/php/FourFix.php' (include_path='/home/xxxxx/public_html/j25/media/civicrm/custom/code:.:/home/xxxxx/public_html/j25/administrator/components/com_civicrm/civicrm:/home/xxxxx/public_html/j25/administrator/components/com_civicrm/civicrm/packages:.:/opt/alt/php55/usr/share/pear:/opt/alt/php55/usr/share/php') in /home/xxxxx/public_html/j25/administrator/components/com_civicrm/civicrm/CRM/Core/ClassLoader.php on line 126
It's referencing file "FourFix.php" which does not exist. I'm stuck and can't continue. I tried updating to 4.4.21, then the database update. Same result. Anyone able to help??
