Multisite Content Copier not copying

Previously the Multisite Content Copier seemed to work, but today I was trying it and it's not working.

Everything appears to work properly. I select the site to copy from, the content I want, the site(s) I want to copy to, and it says it was successfully copied. However, I go to the destination site and the content is not actually there.

I created a new page that I want to copy to other sites on the network. Initially all I was trying to do was copy it to a test site to make sure it copied correctly before copying it to all other sites, but it won't copy.
