I have Twicet installed and it seems to run fine. Been great for a year.
I also have WPML installed, it too has been great but hasn’t been turned on for the general public because not everything is translated. Well, we just got around to doing that and discovered that when any language other than English is chosen—the Image Slider simply doesn’t work.
have_posts() in index.php returns false and the homepage just sits there with no content in the Slider.
