I’m getting error
400 on https://www.example.com/wordpress/wp-admin/admin-ajax.php:
Request Method: POST
Status Code: 400
It happens when I:
- try to install or delete a plugin
- try to update a post
- I also noticed that when I’m on the post overview page (https://www.example.com/wordpress/wp-admin/edit.php), WordPress keeps logging
load-scripts.php?c=0&load(chunk_0)=jquery-core,jquery-migrate,utils&ver=5.7.2:2 POST https://www.example.com/wordpress/wp-admin/admin-ajax.php 400
every 15 seconds to the Google Chrome developer console.
What I tried:
IIS_IUSERSwith full permissions on
- deactived all my plugins
- added debug to
wp-config.php, but very little and nothing of interest gets logged
- Set permalinks to
- plugin Health Check (https://wordpress.org/plugins/health-check/) reports
The REST API did not process the context query parameter correctly.
- Tried reinstalling WordPress and restore my database
What else can I try?
