What did you change the directory from and to? (ie what's the old directory and new directory paths?)
Those last two links look the same to me. And neither show an error.
No...those are child of this parent directory:

yes..these directories are  without error but problem is when i try to change any question in any directory (for example those directories) by admin acount, i get error
(i hit edit buton in question page...i can edit title, text and tagsT but when i try to change direcrory of that question, i see error page!)

thank u for your helping ;-)
