404 not found on config page

Do you see the "Metatag" entry when you go to "admin/config/search" or is it missing? Are you using user 1 or a different user account that might not have the "administer meta tags" permission?

What version of Drupal core are you using? Is your codebase fully up to date? What version of PHP is used and what is memory_limit set to?

same behaviour:

• core 9.2.4 (fully updated, just installed via composer)
• "drupal/metatag": "^1.16"
• php 7.4.22
• memory_limit: 512M

Hello!
Same problem here:

Server: NGINX 1.16.1
Php: 7.3.27
Drupal core: 9.2.5

Logged as user 1.

And if I try to add the metatag field in a content type, Drupal render a 404 page.

I hope this can help toward a final solution.
It's rather an nginx configuration issue.
I'got this piece of fonfiguration in my server bloc, that I had to deactivate for the admin page of metatag to re-appear.
Need more detailed answer not to expose those directories though.
Php, drupal and nginx throw no error.

# Protect files and directories from prying eyes.
location ~* \.(engine|inc|install|make|module|profile|po|sh|.*sql|theme|twig|tpl(\.ph>
deny all;
return 404;
}

drupal-9.2.5
metatag-8.x-1.16
php7.4-fpm
nginx/1.18.0 (Ubuntu)
And I get the same 404 error with drupal8.9.18

I am able to access the Metatag configuration page with the following configuration:

Drupal-9.2.5
metatag-8.x-1.16
php7.4-fpm
nginx/1.18.0 (Ubuntu)

This doesn't look like a metatag module or Nginx config issue to me (Other configurations would have failed as well, if it was due to Nginx). I would recommend using this https://www.nginx.com/resources/wiki/start/topics/recipes/drupal/ to set Nginx with Drupal correctly.

I already use the config file that you shared (https://www.nginx.com/resources/wiki/start/topics/recipes/drupal/).

If remove this line configuration and restart nginx server, I'm able to see the config page:

location ~* \.(engine|inc|install|make|module|profile|po|sh|.*sql|theme|twig|tpl(\.php)?|xtmpl|yml)(~|\.sw[op]|\.bak|\.orig|\.save)?$|/(\.(?!well-known).*)|Entries.*|Repository|Root|Tag|Template|composer\.(json|lock)|web\.config$|/#.*#$|\.php(~|\.sw[op]|\.bak|\.orig|\.save)$

So the problem is in that configuration for me, but why other modules config page works?

Hi, we have the same problem.

Centos 7 x64
PHP Version 7.4.24-fpm
nginx/1.20.1
Drupal 7 (sorry, i don't have the admin privileges to see the exact version)

EDIT: The provider says that nginx is installed, not apache "human mistake"

The "Tag" part in "...Repository|Root|Tag|Template..." is matching with the /admin/config/search/metatag path and goes into the 404 location.

It's there for a reason so I won't advise you to remove the "|Tag" part. Unless you want to.

I was having the same 404 problems on my site but getting a copy of the latest recipe from the nginx wiki fixed it for me. Looks like the regex has been fixed.

Seems like this is an infrastructure issue, rather than something with the module.
