404 admin-ajax.php

    The URL /wp-admin/admin-ajax.php is returning a 404 in the admin screens, for example in Appearance->Themes->Add New->Featured.

    I have checked file permissions and that the file is present and readable, however I get the following response from ajax calls in the admin screen:

    HTTP/1.1 404 Not Found
X-Powered-By: PHP/7.0.7
Access-Control-Allow-Origin: https://dhlvm
Access-Control-Allow-Credentials: true
X-Robots-Tag: noindex
X-Content-Type-Options: nosniff

Content-Type: application/json; charset=UTF-8
Transfer-Encoding: chunked
Date: Fri, 15 Jul 2016 19:46:05 GMT
Server: lighttpd/1.4.39

    The response body looks healthy, which is strange considering the 404 status:

    {"wp-auth-check":true,"server_time":1468611965}

    I have no plugins enabled, just a plain WP installation on a local VM running under lighttpd.
    I did have to set define(‘CONCATENATE_SCRIPTS’, false); in wp-config to fix another issue, so I wonder if this is related (CONCATENATE_SCRIPTS=true makes the admin screens practically unusable for some reason).

    Any ideas as to why I’m getting the 404 errors ?

    Same error appears with Chrome and Safari browser.

    After looking into this a bit more I can see that the 404 responses are being returned for multiple ajax actions posted to admin-ajax.php, for example actions “theme-install” and “heartbeat”.

    The actions all seem to return valid response bodies, but a 404 status.
    For example the response body for “theme-install” starts with:

    {“success”:true,”data”:{“info”:{“page”:1,”pages”:1,”results”:15},”themes”:[{“name”:”…..

    Fixed!
    It was a problem in the lighttpd config – the docroot in the fastcgi config was incorrect.
    Strange how the majority of WordPress worked and that only ajax requests were affected by this issue.
