[jboss-dev] JBoss Portal Exception Error

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. ________________________________________________________________________________ HTTP Status 500 - -------------------------------------------------------------------------------- type
