PHP Error not displayed on Yii 1.0.5

I get debugging problem with Yii 1.0.5. If I write wrong syntax in my PHP Code I will get blank in my browser. But If I switch the framework to Yii 1.0.4 It will display PHP Error on my browser.

How to display all error in Yii 1.0.5?

Yeah, there's a problem in 1.0.5 about this. It has been fixed in SVN.

Oh, thanks Qiang. I will try to download from SVN.
