I've deleted ALL other themes besides the theme that I created using x3 as the basis for. Turned of all the styles except for the root theme which I then modified to show my graphics, etc. Clients are STILL able to chose from the deactivated styles in the theme set I use. In fact, in cPanel when logged in, I have a theme dropdown that shows my theme AND x3 which was deleted! Holy - what a complete mess! This needs serious attention - immediately. Branding is a HUGE part of hosting and not being able to do it PROPERLY is a real drag.
