Since version 2.7, WP uses POST method to request "wp-cron.php?check=...". What is the point ?
My antispam filter works by denying POST method to people who fail to provide proper credentials. It's implemented on the server side (in httpd.conf). Then, the POST method is denied for wordpress or whatever process on the server.
I had to edit wp-includes/cron.php to replace wp_remote_post with wp_remote_get. Is there any surprise like this one elsewhere ?
I need to get rid of every POST requests made locally, and replace them with GET requests.
