I can do it myself, just wondered if its another hidden setting somewhere – it seems such an obvious feature since most installations have SMTP mail ready to go and all users have an associated email address anyway. Maybe you could consider it in future updates.
Narrowed the 3 error lines down to just the login page which is included with the HostWHMCS demo data. I haven’t touched this page yet and on inspection i can see it is set to: http://billing.ywhmcs.com/dologin.php?systpl=HostWHMCSwp – its not that important yet so ill leave it.
Did you check this info is correct? i already know how to edit pages in WP – take a screenshot of the actual location that we can change the text, “Looking A Premium Quality Domain Name?” cos i can’t see it anywhere … if it is possible then it should be made clear in your documentation.
