suzer,
Thanks for getting in touch and sorry to hear you’re having trouble here, but hopefully I can help. In version 3.5.1, we’ve significantly changed the way tooltips work, and consequently you’ll need to update any template overrides that you’ve performed in order for things to function correctly. I’m seeing that you’ve performed a number of template overrides, which you’ll want to update in order to make sure things are working correctly.
Give that a shot and let me know if you have further questions. Thanks! 🙂
