there is a file called opensocial-config.xml
For instance on the Deployment Manager it may be... /local/con/opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/localhostCell01/LotusConnections-config/opensocial-config.xml
<developer enabled="true" allowSSOFeature="true" allowIntranetProxyAccess="true">
<developer-hosts-whitelist allServers="true">
<!--
List of base URLs that are allowed to publish 'developer-mode' gadgets
<host url="http://{host.com}/base/url/1" />
...
<host url="http://{another.host.com}/base/url/N" />
-->
</developer-hosts-whitelist>
</developer>
You want to switch to true enabled allowSSOFeature allowIntranetProxyAccess also switch whitelist AllServers to True
Edit the /local/con/opt/IBM/WebSphere/AppServer/profiles/AppSrv01/config/cells/localhostCell01/LotusConnections-config/opensocial-config.xml
Restart your Connections Server
It should come back up and enable all gadgets posted to render as EE
