Hey Undalkeor,
first of all, thank you for the purchase!
In the case of Sensei demo front page it was simple – I just didn’t fill in the page title field :) In case this is not good enough and you want a cleaner solution, you can go to “Appearance -> Editor” and add this line at the bottom of “style.css” (should be opened by default):
#page-wrapper h1 { display: none; }
or
.page-id-xx #page-wrapper h1 { display: none; }
where “xx” is the ID of the page in question, if you want to hide the heading on just one page; and hit “Save changes”.
Sincerely,
Andrew | Satori
