@francoc30 Do you have any other caching plugin installed or caching mechanism enabled on the server, if so could you please disable the other caching mechanism and check if it helps to fix the issue?
@francoc30 It seems your WordPress update is somehow broke things. The files involved in this Fatal Error are from WordPress core.
You may want to FTP wp-includes and wp-admin folders and overwrite existing one.
Are you on PHP 8.1?
Hi Harshad,
My Cache Control tool on cPanel was disabled long time ago and I have no other cache plugins running along WPO.
Hi Venkat,
I did have WP 6.0.3 updated recently. It appears to me the update cause my site to slow drastically. But not sure if they are related. Is there a way to rollback WP?
What did you mean
” You may want to FTP wp-includes and wp-admin folders and overwrite existing one.”
Where do I get the wp-includes and wp-admin folders to overwrite the existing one?
My current php version is 7.4.10
@francoc30 My guess is that the WP update is somehow broken, i.e. some files misisng.
So download a fresh copy of WP https://ww.wp.xz.cn/latest.zip
Unzip it, it will contain wp-admin, wp-includes and wp-content folders. Copy everything except wp-content folder and wp-config.php file from your computer to your server using FTP client such as FileZilla.
Hi @webulous,
I have downloaded the latest WP. Just want to be sure I understand what you suggested:
1) replace all files (not under any subfolders) in the wp-admin folder AND all files in the subfolders of wp-admin.
2) replace all files (not under any subfolders) in the wp-include folder AND all files in the subfolders of wp-include.
3) leave wp-content folder and its files as is (not to replace).
4a) leave all files under parent folder WordPress as is, OR
4b) replace all files under parent folder WordPress except for wp-config.php
I am not clear on #4, whether it should be 4a or 4b.
These file replacement process would not adversely affect my website setup, correct?
Hi @francoc30
The error happens from files with wp-includes folder. So, replacing that (#2) is suffice. Just to be sure, follow all steps you have listed and for #4 it is 4b
> These file replacement process would not adversely affect my website setup, correct?
Yes, the site related files are in wp-content folder and in wp-config.php file.
But always take a full backup before proceeding with UpdraftPlus

@webulous, thanks for the clarification. I’ll get it a try when I have time.
