[xwiki-users] XWiki 2 ML 4 .xar import error

Hello everyone, Tried setting up XWiki 2 ML4 as a fresh installation on a test machine. The installation went fine. However, importing the .xar file for XWiki 2 ML 4 throws the following error: Wrapped Exception: org.apache.velocity.exception.MethodInvocationException: Invocation of method 'save' in class com.xpn.xwiki.api.Document threw exception com.xpn.xwiki.XWikiException: Error number 9001 in 9: Access denied in edit mode on document XWiki.XWikiPreferences at /templates/admin.vm[line 58, column 26] at org.apache.velocity.runtime.parser.node.ASTMethod.handleInvocationException( ASTMethod.java:337) . When I tried again, it takes me to the XWiki preferences page but the page says it is locked in edit mode by XWiki.Guest. Clicking force edit throws the above mentioned error again. Is anyone else too facing the same issue. Did I miss out on anything critical during setup. The machine is the same where a test version of XWiki 2 ML 3 works just fine.
