Hi there,
I’ve been using the query builder to display CPT on our website for years. Somehow, the builder doesn’t function anymore. For testing purposes I’ve but date published after on 1 August 1900, and it still shows data. I can guarantee you that we didn’t post anything before 2000 
Our website is fully up to date and all caching has been fully disabled. Funnily enough, it does actually work for sections where I’ve already set the query builder up. But any changes mess it up completely.
The problem occurs both on the homepage in a looper provider as on the archive page of the CPT.
