I'm using twentyten as my template and make a custom-template for one of my page. there is no problem up to this point, the custom-template is applied and it's showing just fine.
A few days later, I made another custom-template for a new page which I'm planning to make. but when I arrived at the 'Edit Page' window, I couldn't find the page-template option in the 'page attributes' tab!
I checked the page with custom-template which I made a few days ago (the one mentioned in the first paragraph), and it's still working fine. But now I no longer could change my page template since the option is gone...
can anyone help me to solve this problem?
