Yes – while this is an excellent plugin (I use it across a few sites and really like it), this recent update is absolutely untested and WILL break your site.
The reason for the content error is a content filter that has been added to the “the_content” wordpress method. If you go to the plugin directory/index.php line 591 and comment out that line it will fix your content issue. Also, just comment out line 63 and 64 (this will stop the plugin’s JS from loading – I’ve found it has conflicts as well).
Now for the other JS error – if you go to the plugin folder/fieldTypes/class-gallery.php and comment out lines 79-86 and 90-94 that will fix your JS error. It will likely break the added Gallery functionality of the plugin, but it will stop breaking your site until the plugin author releases another patch 🙂
