It looks like the latest version of WordPress 5.0.3 has destroyed our individual Chicago dog parks pages (which were using the Multiple Content Blocks plugin). Crap.
We’ll try working on reconstructing them, but so far… oof. This is tough news.
Update: reverting to v4.9.9 has saved us, so far.
Update: looks like there’s a workaround – will deal with this over the weekend.
