Good question....

What version of PS are you using, is it an upgrade or a clean install?
Did you make any changes anywhere?

[MAMAY]

1.4
Clean install, but i make many changes.
Problem at me for a long time, only I didn't include display of errors earlier. Strange, but she dares template change, with the standard. Each time it is necessary to change a template before manipulations in this section.

I'm sorry, but I don't understand what you mean.

I suggest you try to undo your changes (keep a backup) until you find which file caused the problem.
