blank posts in admin panel

I forgot to attach screenshot, https://dl.dropbox.com/u/13234407/WordPress_1.png as you can see all fields are empty, but text must be there. Also when I load the page I see for one second all text, and after it’s going out.

Have you tried:

– deactivating all plugins to see if this resolves the problem. If this works, re-activate the plugins one by one until you find the problematic plugin(s).

– switching to the Twenty Eleven theme to rule out any theme-specific problems.

– resetting the plugins folder by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems.

– re-uploading all files & folders – except the wp-content folder – from a fresh download of WordPress.

Nope, I can just wondering about it =(
It’s site that work in production, I can’t switch between themes or re-upload files (

I am sure it’s about some plugin, I was searching on this forum a lot, but still did not find some problem, that is close to mine issue.

But I will try to re-upload all files… except wp-content folder..god bless me ))

Okey, I did find where is problem. It is happens because of this plugin: qTranslate

The problem is that I need it and can’t just switch it off =(
Continue investigation…
