I have updated my WordPress using qTranslate plugin to 3.5 version Today, and qTranslate works incorrect:
"The qTranslate Editor has disabled itself because it hasn't been tested with your WordPress version yet. This is done to prevent WordPress from malfunctioning. You can reenable it by clicking here (may cause data loss! Use at own risk!). To remove this message permanently, please update qTranslate to the corresponding version"
