Need help – Edit posts loads a random post

Today when staff members went to edit their blog posts they were all loading random posts, a different post each time

Even a “new post” loads up a random post

We use classic editor plugin, V 1.6.3

• AWS ec2
• WP 6.2.2
• PHP 8.1.16
• Apache/2.4.57

Here’s a big dump of info/debugging the other guys and I have done

the id in the url is correct, but the post it loads isn't

The front end loads the correct post

wp-admin is also really slow, the front end is slightly slower but not to bad

When we've had this in the past its been the DB, wp-options needed a repair
That doesn't seem to be the case this time
I ran mysqlcheck on all DB's and no issues

we're seeing these errors sporadically in the apache error_log, I can't find a way to trigger the errors though
Lock not acquired

Error reading Wordfence Firewall config data, configuration file could be corrupted or inaccessible. Path: /var/www/html/blog/wp-content/wflogs/config-synced.php

Cron reschedule event error for hook: wf_scan_monitor, Error code: could_not_set, Error message: The cron event list could not be saved., Data: {"schedule":"wf_scan_monitor_interval","args":[],"interval":60}

Despite the wordfence error it can write to config-synced.php, the modified time keeps updating

The file permissions were also off, e.g.
-rw-rw-r-- 1 500 apache 7.1K Nov 7 2022 wp-activate.php
drwxrwsr-x 10 500 apache 6.0K Feb 14 2022 wp-admin
-rw-rw-r-- 1 500 apache 351 Apr 6 2020 wp-blog-header.php
-rw-rw-r-- 1 500 apache 2.3K Feb 14 2022 wp-comments-post.php
-rw-rw-r-- 1 500 apache 3.2K Nov 13 2021 wp-config.php
-rw-rw-r-- 1 500 apache 3.0K Apr 18 22:23 wp-config-sample.php
drwxrwsr-x 10 500 apache 6.0K Feb 3 2021 wp-content

I've reset them using
sudo chown -R --from=500 ec2-user /var/www/html/blog/*
sudo find /var/www/html/blog/wp-content/cache -type d -exec chmod g+w {} \;
sudo find /var/www/html/blog/wp-content/plugins -type d -exec chmod g+w {} \;

but the issue continues

I used the wp crontrol plugin to look at the crons

wordfences tools -> debug shows crons have been failing since (this is the first recorded failure) (this is Sydney Australia time)
Sun, 25 Jun 2023 22:25:07 +0000 (Overdue)action_scheduler_run_queue

The error wp Crontrol says is 
cURL error 28: Operation timed out after 3000 milliseconds with 0 bytes received
Which makes sense since wp-admin is running slow

I rebuilt the indexes with mysqlcheck –optimize

One of our developers said he’d seen similar when wp-posts didn’t have an auto increment, I checked all of our tables and they look fine

I’ve turned on the debug log but there’s only some php deprecation warnings in there, nothing that looks suspicious

Uploading images via media library they end up in a random directory under upload each time. e.g 2020/04/

I looked for changed files/directories in the last 24 hours, there’s a few things like

• ./wp-content/wflogs/.nfs218cdd894e6e333100003756
• ./wp-content/cache
• ./wp-content/uploads
• wp-content/upgrade/ (nothing in here so I don’t know what/if anything was in here)

The block editor doesn’t seem to have the same random post problem, still really slow because of whatevers going on though

I’m pretty much out of ideas so any suggestions anyone might have, please offer them
