Nginx Rewrite problems after 5.2.2 was released.

[mitchellk]

I've been running WordPress on Nginx for over 2 years without fail.

Exactly on June 18 2019 when 5.2.2 was released large amounts of rewrite errors popped up on every single site.

This problem was not noticed until a week ago when I got several thousand errors in Google Search Console that my sites were all giving 404 errors.

None of my nginx virtualhost configs have changed in 2 years and Nginx was last updated several months ago.

Viewing the pages reported by Search Console as giving 404 showed they all worked just fine in a browser but in the backend every single pages access was generating an error in the error.log as follows.

"/var/www/mysite.com/my-pretty-permalink/index.php" is not found (2: No such file or directory)

I do not use index.php as I have my permalinks structured as /%category%/%postname%/

But exactly on to the day I updated this error appeared on every single site.

So /index.php started being tagged onto everything in the backend.

Did something change in any of the changes in 5.2.2 that could have caused this?

Hi there, thanks for the ticket!

Replying to mitchellk:

Here's the list of changes in 5.2.2:
https://core.trac.wordpress.org/query?status=closed&group=resolution&milestone=5.2.2

At a glance, I don't see anything that would cause this. There were no changes to rewrite rules or permalink structure handling.

Hi @SergeyBiryukov yes I looked there too and did not see anything but I cannot explain this.

Nginx and PHP have not been updated on this server in some time.

Could it possibly be a Yoast problem ???

That's the only other plugin I use on all sites that ever has anything to do with rewrites.

Hi @SergeyBiryukov you can close this. I think I have found the culprit. It appears others have seen this too with Yoast, something with sitemaps that got broken causing /index.php to be added onto the end of everything. Not sure how because the sitemap itself does not show any links ending in /index.php but in the backend of Nginx every single call to something from the sitemap by GoogleBot was requested with /index.php
