I’m having the same issue. Got this message (Notice: Indirect modification of overloaded element of WP_Hook has no effect in /home/content/p3pnexwpnas07_data02/84/2485484/html/wp-content/object-cache.php on line 664) from WordFence this morning (same information 7x repeated in the email).
I called GoDaddy and according to them line 664 is related to caching. I was told that both my WP plugins & GoDaddy are trying to both flush my cache and that’s most likely the problem and causing a conflict but they don’t know. I sent them the email I got and I sent them this thread to look at. My entire site all day was a mess, all plugins stopped functioning and the entire site went down for no logical reason. After they told me that they didn’t know what was wrong they told me that I must’ve been hacked – this is right before their restore API went down today.
After having spoken to them pretty much I decided to wait it out then restore my site (as I think the issue is on their end not mine – due to me only having really messed up site issues since their purchase of Managed WP and they’ve had plugin integration issues in particular).
I just restored my site a little while ago to get it back up and running and in WordFence I have this message showing in detailed activity: Notice: Indirect modification of overloaded element of WP_Hook has no effect in /home/content/p3pnexwpnas07_data02/84/2485484/html/wp-content/object-cache.php on line 664
In “New Issues” I’ve Got The Following Showing:
WordPress core file modified: wp-includes/load.php (CRITICAL)
Unknown file in WordPress core: wp-includes/theme-compat/comments-popup.php (WARNING)
Unknown file in WordPress core: wp-includes/js/tinymce/wp-mce-help.php (WARNING)

Unknown file in WordPress core: wp-admin/js/wp-fullscreen.min.js (WARNING)
Unknown file in WordPress core: wp-admin/js/wp-fullscreen.js (WARNING)
At this point I feel like this is all a GoDaddy issue but I don’t know. I just need whatever’s going on to stop and need to know how to fix and prevent it as my entire site got ripped apart and rendered useless today.
Any help would be greatly appreciated.
Thank You,
