I am not sure that it is a java issues as the map on this site works fine. I am most worried about the failure of the xmlrpc php files to work properly.
It looks as if other people have these working on their sites, but I get the php error
Fatal error: Cannot redeclare xmlrpc_decode() in /var/www/html/tikiwiki19/lib/xmlrpc.inc on line 1017
Could this be because I have updated the database several times through several editions? This seems unlikely as it is only the database that remains from these earlier versions.
