Cannot load the ionCube PHP Loader - it was built with configuration 2.2.0, whereas running engine is API220090626,NTS
This PHP error is being caused because IonCube is trying to load the old version. To update this on Debian:
EDIT: /etc/php5/conf.d/aa_ioncube.ini
FIND: zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.2.so
REPLACE: zend_extension = /usr/local/ioncube/ioncube_loader_lin_5.3.so
This error was caused when upgrading from PHP 5.2 to 5.3, I wanted to make sure no configuration files was overwritten. So when upgrading via apt-get, I made sure to always select the option for the local configuration files.
