You can remove Content Title on the page editor in the Disable Elements box.
If you have a lot of pages already created there is some PHP on this forum to do so….. just cant find it at the moment.
Sorry to jump in, but this option is only available for admins, not for editors. Since it is content (titles and more) i think the option ‘disable elements’ should be available to editors too.
I can not find a straight forward approach to achieve this.
Any suggestions?
