[Plugin: WP Smush.it] Http error with WordPress 3.3.2

Apparently the problem has come back. Tried to upload photos on my site https://adondeirhoy.com but kept getting the HTTP Error

Disabled Smush.it and everything works fine again, except my images are no longer optimized.

Hope they fix it again. Here is the conversation of other members having the same issue.
