Unfortunately our crystal ball seems to be broken so we can’t guess what version of the plugin you’re using, or browser, or your site’s URL, or anything for that matter.
Please invest more than 2 seconds when reporting a problem and describe it properly so that it can be reproduced and fixed. Thank you.

It’s a fresh Chrome issue – http://ww.wp.xz.cn/support/topic/problems-with-chrome-v30?replies=1
