Hi. Kindly help. We were configuring the look and feel of our JBoss
Portal...changing the portal layout, theme and rendering using the Admin
page. When we re-freshed the portal page. The error below was displayed.
We don't know how to fix it as we were updating the configuration using the
GUI and we are not developers. Please advise on which files we should look
for to do the fix. Thanks.
