Thread:Project:Support desk/Moving mediawiki 1.10.0 from Windows 2003 server to RHEL 6 server/reply (5)

Ok, I copied all files from the old wiki directory to the new wiki directory using the command cp -rnf /var/www/html/oldwiki/* /var/www/html/newwiki  That seemed to work. the n option should make sure that versions of a file in the newwiki directory are not overwritten. However I am still getting a blank page. In the /etc/httpd/logs/error_log file, I see the follow messaage: "PHP Fatal error:  Call to a member function addMessages on a non-object in /var/www/html/mediawiki/extensions/NewestPages/NewestPages.php on line 40"  I did a google search on that error message but couldn't find much that was helpful. Does anyone know what I should do from here? Any help is greatly appreciated. Thanks!
