Hovercards and other hover over image functions don't work anymore!
<p>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.</p>

<p>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 :(</p>

<p>As I'm a total beginner I'm not sure, but I think both (hovercards and the mentioned plugin) work with javascript? So maybe something is interfering with that?</p>

<p>I hope you can help me figure this out.

<p>Thanks a lot in advance for any kind of advice! :)</p>
