Will CB and CBSubs work with version 4.0.12?
Probably not.
Is there anyway for you to provide ioncube configuration you used in this thread?
No, PHP.ini is site specific. You need to upload the ioncube folder from the ioncube package to your Joomla root. Then add a php.ini file to your Joomla root that contains the following.
[IonCube]
zend_extension = "HOST_ROOT_HERE\IONCUBE_VERSION_FILE_HERE"
Then also add that same php.ini to root/administrator. It should then work fine. If you have any problems then please contact your host and have them upgrade ioncube for you.
