OK, I think I’ve found the issue and it’s essentially the same issue as one we had with the forms a couple of weeks ago.
Again, this seems to be an issue with Chillidog hosted sites due to the security settings they now have. I’ll need to do some work on our end to provide full compatibility with Chillidog hosted sites and the Load More component.
I’ll get this update done ASAP, although it’s not going to make it in to the next release it will hopefully be in the one after!
