6.2 Internal Server Error on bib shortcode

I think this started with the update to 4.8.1. 6.2 I’ve already tried to clear the cache from the account page.

Administrators appear to be able to load these pages just fine when logged in, after the cache was cleared; even site Editors continue to receive the same issue after cache clearing. A normal visitor also experiences this problem.

Here’s a Pastebin of the Console error:

I’m seeing the same error on 3 different sites.

I’ve double-checked folder permissions and things look OK.

I’m going to try reverting to the previous version and see if the error goes away.
