Following.
WordPress core file modified: wp-includes/load.php
Notice: Indirect modification of overloaded element of WP_Hook has no effect in /home/content/p3pnexwpnas13_data01/82/3090882/html/wp-content/object-cache.php on line 664
I see GoDaddy mentioned, and I host on MediaTemple which is also now a GoDaddy company if I’m correct. Since we cannot modify core files, I assume we wait for our host to recognize and fix the cause of this error?
Updated to Wordfence 6.2.7 and received the warning Unable to accurately detect IPs as everyone else here has.
I worked my way through this documentation with no luck
https://docs.wordfence.com/en/Misconfigured_How_does_Wordfence_get_IPs_notice
Checked IP ranges, plugins, IP syntax (commas), settings, etc.
Still looking for anything else to try.
