Viktor,

If you encounter this problem again, please let me know so I can make an actual fix for it.
For now, I'll mark it not-a-bug since it resolved by itself.

Are you sure that exim4.conf was exim:exim 644 before? If you just make changes to it, it will get overwritten when you create new mailbox. Instead, use Advanced tab in Mail section to add custom config parts.

Please a) post versions your Ajenti packages (especially ajenti-v-mail) and b) check the owner, group and mode of /etc/exim4/exim4.conf

Check the status of self-tests visible on main Websites page

I suggest trying to set WP_HOME or WP_SITEURL appropriately in the wp-config.php file in your Wordpress directory.

Plugin only works with stock CentOS BIND9 package, which has its config in /etc/named.conf

Sorry, not happening anytime soon. Shared / reseller hosting isn't a goal for Ajenti V

А как выглядит вывод sudo sensors?
