Errors after install: Cannot instantiate non-exist

[caldia]

After fresh Joomla install and install of XMap

Cannot instantiate non-existent class: xmapconfig in /var/www/vhosts/site.com/httpdocs/administrator/components/com_xmap/admin.xmap.php on line 69, referer: http://site/administrator/index2.php?option=com_sef&act=aliases

In admin area and off component link---page draws as a white page--nothing showing???

Hi, which sef component are you using? And... which version of joomla? Exactly what are you doing when thats happens?

Thanks!
