Hi,
I could see that you are using old version of libraries. We have upgraded our software. You should need to upgrade your script for the php version 5.3.24 and use below libraries instead of old one
=================/usr/local/IonCube/ioncube_loader_lin_5.3.so/usr/local/Zend/lib/Guard-5.5.0/php-5.3.x/ZendGuardLoader.so=================
What does this all mean?
