Oh, I thought you just wanted to remove the title, not the whole content area. That is something else entirely so first restore the above code.
The next thing you will need to do is go into the template manager and in the profiles tab make a copy of the profile you are using. In that copy under you will see in the “Global Settings” an option called “Hide main content block”. Set that to yes.
Then got to the “Global” tabe and in the section “Profile Override Settings” click on the “Click To Add” box on the left and select the pages or sectins you want the content box hidden on, Then in the rigt box select your new profile from the dropdown.
Finally clear the jat3 cache and in some cases any cookies set by your site and you should be good to go.
