Hi,
I suspect the solution of your problem is to set category security permissions as follows:
Admins: Create/Reply/See
Everyone: Reply/See
if that doesn’t help, You may have to disable the title editing in admin settings. If you don’t mind, I’d move this question to support since this isn’t really a marketplace project. If you want to hire someone to do it for you, I’ll be able to take this, I’m English speaking.
