Better update to 7.0 because 6.5.1 incarnate to 7.0 and always update.
Update with 'yum replace mratwork-testing --replace-with=mratwork-release; yum replace kloxomr --replace-with=kloxomr7; sh /script/cleanup'.
If not work after cleanup, need re-install with 'sh /script/upcp -y' and then re-setup in 'switch programs', 'php configure' (in 'admin > servers > localhost > php configure'), 'php type' in 'webserver configure'.
