Comment (by dmsnell):

 Hm. It does sound like this could be a problem introduced by some plugin
 if it doesn’t happen on your minimalist test environment, though that
 doesn’t necessarily have to be the case.

 Given that @siliconforks mentioned the existing issue for the 404 page,
 this may be hard to figure out unless we can identify specifically what
 triggers the issue.

 If you can find a specific plugin causing the array-to-string error to
 appear, you might reach out to that plugin for support on their side to
 fix the issue. While I definitely want us to figure this out, I do want to
 reiterate that I think adding type checks at runtime for situations that
 aren’t supposed to occur (and which in this case are well-documented) is
 something that would be good to avoid; there is no end to that direction
 of code unfortunately.
