It should happen automatically each time you create a custom template. As far as I know, nothing should be hiding those templates. There might be some issue with your hosting provider.

You would tell them what your problem is, and ask them to check to see if there's any issues with your service.

I think you just need to re-read the instructions, they work. You don't need to look for "Custom Templates" just "Add New Template" and it will be custom.

yes its working that, but the PROBLEM its when i want to edit the template, :erm:

What is the problem with editing the template?

as i mention before, i create template put some words on it and save it, its show with the php file as on the 1st post
but later when i want to edit it i dont see it (and all custom templates) and even when i search with some words i know there are on the template :(

Are you sure you aren't accidentally clicking revert on it at some time?

You should check your error_logs and see if anything is in there about the issue. And, check your control panel logs and see when it is getting deleted. And, check your database to verify it really isn't there.
