μπορεί κάποιος να μου εξηγήσει τι σημαίνει Warning: filemtime() [function.filemtime]: stat failed for themes/zen/comments.js in

You're not alone here..

Could you give us some details? Does it happen when you add a translation?

yes or when I am going to do a requested translation.but now I don't see it any more

I see. It happens kinda randomly, though.

mmm...but it was the first time seeing it so I thought it should be better to ask someone..

Can't reproduce it at the moment, will try more later.
