Application Error in my HTC Desire

I created an application in a certain website for my HTC Desire Android Smartphone, but I got an application error when loading it.
I tried it on other phone such as Samsung Galaxy Ace and it’s working perfectly fine.
But I can’t make it work in my HTC phone.
How can I fix it?

Application Error
The connection to the server was unsuccessful. (file:///android_asset/www/index.html)
