I just posted to cPanel support, I am not sure if this is a bug or not.

I am trying to change the main shared IP address of a server but its not going through.

I am running WHM 10.8.0 cPanel 11.0-E512

Changing main shared IP on Basic cPanel/WHM Setup and after trying to change a sites IPs addresses under Change Site's IP Address the Current Address still the old one.

Anyone can please test and let me know if the error ocurrs ?
