From 2d12c86d823e2466073c9a38df0d99f8dcc73e63 Mon Sep 17 00:00:00 2001 From: Aaron Jorbin Date: Thu, 15 Oct 2020 17:05:48 +0000 Subject: [PATCH] Bootstrap/Load: Don't assume WP_CONTENT_DIR is defined When the mysql extention isn't loaded and a custom db dropin is not in place, we give folks a nice error. However, we can't assume that the WP_CONTENT_DIR constant is set yet since this runs before we define default constants. This fixes a PHP8 error.
