[1.7] How to hide titles on CMS pages

you can hide with custom css code(you can paste code in backoffice > themeeditor > custom css field)

#cms .page-header {

display: none;

}

or if you want to hide only for one cms page then you need to base on cms page id. Ecxample

#cms.cms-id-2 .page-header {

display: none;

}
