Akeeba Admin Tools does a great job securing our client's joomla websites. Komento is our current go-to commenting extension since it integrates with Joomla articles and K2 items.
However, we have found that Akeeba Admin Tools is doing too good of a job and actually preventing Komento's "AJAX" calls when a post is being made.
We like to set up the new account and transfer the old site into the new account before we change the DNS settings. Unfortunately, Hostgator does not allow Akeeba's Site Trasnfer Wizard to funstion without an actual domain name on the new account.
