Try turning on WordPress debug:

to see what kind of message it returns.
Thank you for reply and i tried not works ! i do not know why !!
It’s possible that the errors are saved in an error log file. Ask you host to see where the log file is.
Can return old version ? 3.4.1 to back 3.4.0 ?
You can try to upload 3.4 files, overwriting them, but it’s not recommended. I have installed 3.4.1 like million times, never had similar problems, so I believe the issue is caused by something else, not the WP core.
I want try to 3.4 then upgrade new version, so how i update old version 3.4 ?
There is no going backwards using WordPress itself. You have to upload the 3.4 files to your site again (never tried this myself though).
You can find the old versions at
http://wordpress.org/download/release-archive/
i want say thank you for helpful and i update 3.4.0 now works back to normal ! seem 3.4.1 have bug or issues so now everything back norman running 🙂
Wow, glad that fixed the problem, that’s a surprise. Strange that I never had problem with 3.4.1, but maybe you have a plugin or your theme is not totally compatible with 3.4.1.
But usually you can find the error message in the error log, so you know what to look for for future upgrades.
Have a nice day!
