This problem is driving me crazy. So, I've Jetpack installed and the Gravatar hovercards activated. I could live without them, but other "hover over image" functions (e.g. I'm using the Guan Image Annotation plugin that lets you add a note to an image in a post by hovering over it) don't work either.
It still worked earlier today and all I did was activate and deactivate a few other plugins. I tried to figure out with plugins are causing the misfunction, but couldn't figure it out. Maybe it's not a plugin interfernence after all. I just can't seem to figure it out :(
I hope you can help me figure this out. My (under construction) website is here.
Thanks a lot in advance for any kind of advice! :)
