From 93a325ccf8121d0b5b102914e8989968408961e1 Mon Sep 17 00:00:00 2001 From: Sergey Biryukov Date: Thu, 15 Oct 2020 21:14:35 +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 PHP 8 error. Props jorbin. Merges [49161] to trunk.
