# wp-comments-post.php not reading REQUEST_METHOD correctly

 * An install that has been working just fine for 2 years has developed an intermittent
   problem. Sometimes comments are lost and the user gets a blank 405 error screen.
 * I’ve narrowed it down to this line of code in /wp-comments-post.php
 * `if ( 'POST' != $_SERVER['REQUEST_METHOD'] ) {`
 * Even though var_dump’s show that REQUEST_METHOD is “POST”, this always is true
   and the code throws an error. I can fix this by changing it to :
 * `if ( ! 'POST' === $_SERVER['REQUEST_METHOD'] ) {`
 * …which is probably totally the wrong logic to stop bad requests getting in, but
   why is this working?
 * And how can I fix this without changing this file every time I update WP?

 * Both PHP errors and database errors can manifest as a white screen. This problem
   can be caused by a variety of issues, including:
    (1) Bad theme (2) Bad plugin(
   3) Bad install/upgrade (4) you exhausted the memory limit (5) It could also mean
   that there is an issue with your web hosting server.
 * – 1 and 2 are more common.
    – Since the problem can be caused by any number of
   things, check the error logs on your server for a more specific error message.
   If you need help locating them, ask your hosting provider to help you with that.–
   If you cannot find error logs or if you don’t find any helpful info in them, 
   try adding the following code to your wp-config.php directly _above_ /* That’s
   all, stop editing! Happy blogging. */ : define( ‘WP_DEBUG’, true); – Try reviewing

 * Thanks [@t-p](https://wordpress.org/support/users/t-p/) but this is a core WP
   file that, at this line, has not even loaded WordPress. So it cannot be a bad
   theme / plugin, it hasn’t even loaded the database connection yet and the memory
   footprint is 1.56KB at this point. So I don’t think it’s those.
 * Oh! and there are no PHP error messages, even with WP_DEBUG on (it hasn’t loaded
   WP yet)
 * I thought it could be the hosting environment but if I add `echo var_dump($_SERVER);`
   after the headers that return the error. I can see `'REQUEST_METHOD' => "POST"`
   so it must be getting through to PHP but something is triggering this error.
