I just noticed the patch about the sub-template and the copy function. But I just noticed this when I created a new template withOUT copying from an existing template. The Dashboard seems to display that the new sub-template has no .php after the name.
I am attaching screenshots. I have 2 sub-templates shown, one has nothing in the file and another I just manually pasted in postformat.php code.
I'm going to poke around some more and see if I did something wrong. I haven't installed the patch either yet, but the patch seemed to only apply to new sub-templates that are copies of old ones.
Thanks in advance.....
