Uncaught TypeError: $jSpark(…).sparkline is not a function

Hello,

when I am editing a post javascript is not working anymore (so mouse over menus etc do not work anymore in the backend). Chrome Dev Tools (F12) show me the following:

Uncaught TypeError: $jSpark(...).sparkline is not a function

I searched for “$jSpark” and “sparkline” and only found it in the WP-Piwik plugin.

It looks like something is breaking something here. ??

If I can provide any further information, I am happy to provide it.

Thank you for your help,
cheers,
Martin
