lots of errors.

When I run xwiki ./start_xwiki.sh I get lots of errors when browsing, e.g. 11:53:12,807 ERROR P1-19 http://localhost:8301/xwiki/bin/view/Main/WebHome SimpleLog4JLogSystem:logVelocityMessage:143 - Left side ($objuser.getProperty("usertype").value) of '==' operation has null value. If a reference, it may not be in the context. Operation not possible. [line 10, column 66] or 5 ERROR P1-12 http://localhost:8301/xwiki/bin/view/Panels/PanelWizard?forceLeftPanels=1&a… SimpleLog4JLogSystem:logVelocityMessage:143 - RHS of #set statement is null. Context will not be modified. [line 9, column 1] etc. Is this normal? thanks, Dave. -- Dr. David Holden. See: <http://www.gnu.org/philosophy/no-word-attachments.html> regarding Word or PowerPoint.
