Sometime yesterday my forum stopped receivng (or accepting?) new remote topics or posts. I'd spent time yesterday playing with plugins and permissions, so I've been rolling back those changes this morning, but it hasn't resulted in the resumption of content flow.

The only thing the logs indicate is that the forum was receiving dislikes and didn't know how to handle them (at some point, I denied the federated user group the ability to downvote), but last night it just stopped complaining about this. I assumed at this point maybe I'd been spamming some kind of error at the other servers and got blocked or something, but I can still chat (two way) with my remote accounts, and remote accounts can see my posts on the forum. I don't receive any replies, though, weirdly enough, I do receive likes/upvotes.

Are there other logs I should be looking at to make sense of this?
