If you receive the error "Warning: No license for this product ('i365rs') - make sure zend_optimizer.license_path is properly configured in php.ini!" then Cortex cannot read its license file. To make sure your license file exists check C:\i365 in Windows or check /usr/local/i365/etc in Linux for your license file. If it doesn't exist please contact your system administrator, or if you are the administrator please open a support ticket in Orbit so we can correct it. If the file exists try to restart the Cortex web server and reload Cortex in your web browser. If you still recieve the error please contact your system administrator or open a support ticket to investigate it.
