Hi Kyle, thanks for the reply.
Yes, system is green, active.
I had cpanel recreate php.ini with ioncube.. it has these lines uncommented:
zend.ze1_compatibility_mode = Off
zend_extension=/usr/lib64/php/zend/ZendOptimizer-5.2.so
I copied the php.ini to public_html/administrator/
cbpainsubsbot is installed, published, and public.
Global settings are as you've indicated.
Still no go..
