Hi,
Yes, when trying to insert an image into a post, the media library hangs and no images load.
Here’s a screenshot of this, plus the JS console: https://www.sugarsync.com/pf/D6153805_98227535_6924655
The error is “Uncaught TypeError: Cannot read property ‘length’ of undefined”
Thanks!
Have exactly the same problem on site http://community.dur.ac.uk/reed.ne/
Using Version 5.56 of WP Google Maps Pro, and WordPress 4.2.1.
The base version of the plugin works fine, but like @microlivin when activating the pro version the media library won’t load images.
