IBM Connections 5.0 CR1 next gen theme not displayed

After i setup the IBM Connections 5.0 CR1 i open the homepage and the theme was show as the old IBM Connections theme not the new one.

I found on the systemout.log the following

net.jazz.ajax.internal.util.TraceSupport warn The StyleSheet "com.ibm.lconn.core.styles.oneui3/base/applications/profiles"

To solve the problem shutdown the connections server and clean the temp folder of the websphere application server on all nodes.

Restart the server and everything must be ok.

Thanks to Michael Urspinger tip
