[plugin:Nextend facebook connect] blank page after clicking

Hi there ,

I’m actually a wordpress user ( really ?! T___T )

and I’v got a problem with Nextend facebook connect pluin…

I think it’s actually a great plugin..
(and i don’t want to change for another one)

But when I click on the “REGISTER” , “LOGIN” or “LINK ACCOUNT” button (any button..) , I see a blank page…. oO
got this link bellow :
“http://vps-301952-101.virtual-info.eu/wp-login.php?loginFacebook=1”

you can try by yourself… I’v checked my Facebook API , and i’m sure i did’nt put any space with the code…

does anyone have a fix for it ?
or maybe I just do something wrong

Thanks 🙂
