I've been using the dev version of Field Collection for about a week, with no problems. But yesterday I noticed a fatal error on most pages of the website I'm working on:
Fatal error: Call to undefined function entity_revision_is_default() in /data/disk/b3share/static/ncjw-015/sites/all/modules/contrib/field_collection/field_collection.module on line 303
There is one content type where I've added the Field Collection module: Page. And it's throwing this error on every page, whether I've uploaded anything via the Field Collection widget or not. Other pages, such as the homepage, contact page, and admin pages, are fine.
I see someone mentioned something similar here. So I updated to the latest dev version today (which presumably fixed that problem), but am still seeing the issue.
Any advice will be much appreciated!
