I have that file in modules/system/templates/
It had permissions 644 which I have now changed to 744 so it is the same as the other files in that directory.
I am not using a custom template set, I am using the default template set.
Was I supposed to run some update script after installing the 2.0.9.2 to 2.0.10 patch?
(Edit: It's still not working.)
