Upgrading EOC 1.5 RC1 and later to any later versions (RC2 or RTM) causes the WPM menu to be shown under the Network tab.
EOC 1.5 RC and WPM module
As a workaround, the WPM menu can be moved to the Server & Application tab by editing the Manage Menu Bars setting.
WPM should be removed from Administrator_Network and Guest_Network, and added to Administrator_Applications and Guest_Applications.
This workaround is needed when EOC 1.5 RC1 is installed and the user upgrades to any later versions of EOC. It is not be needed if you have not installed EOC 1.5 RC1 at all.
