In r12.2 the default setting for the web interface is secured. But if your port is not secured then you will
get the No Cookie Support error--which is misleading. To resolve it you should follow these steps:
a) U on $NM WEBCENTER Web Interface Controls (on /PARMS)
b) Change the value of Enable Secure URL Prefix to NO
c) PF06 to ACTION
d) PF03 to SAVE
e) Also: Use http instead of https for the WebCenter URL.
