Hello,
Just updated the plugin to the latest version on both sites I'm maintaining for somebody else and A LOT of problems occurred.
On http://johnfrusciante.com, images are not showing in the stores (which are otherwise functioning) and this is the error I get in the backend:

Example of images not showing:
http://johnfrusciante.com/store/letur-lefr/
On http://recordcollectionmusic.com, ALL my custom queries are screwed up - the custom post types and the slides don't display at all:
http://recordcollectionmusic.com/
http://recordcollectionmusic.com/label/
http://recordcollectionmusic.com/production/
http://recordcollectionmusic.com/artists/
As you will probably notice, only titles of custom post types are showing; nothing else.
In addition to this, Jetpack stats are not working on either of the sites after Topspin plugin upgrade.
The themes I created for both sites are valid according to the Theme Unit Test; javascript and CSS are fetched the right way and whatnot. So; it's not me.
I would appreciate a heads-up on this as soon as possible; as the label obviously needs their websites to function and I'm helpless in this particular case. Thank you.
