How to fix WordPress 404 Error on saving a new post or updating a post?

Pawan — Fri, 12 Oct 2018 16:59:09 +0000

I was working on a blog post and had written a part of it and saved it. After some days, I visited the post again to complete it but it would not save, clicking on "Save Draft" button displayed a 404 not found page.

I tried to edit the post with same new content multiple times but same 404 error. Then, since I already had some post content saved, I tried to save it again with no update; it worked. So, I started updating the post content in steps, it was working and content was saving.

I was creating a child theme for a wordpress theme. I created style.css file in child theme which overrided some of the parent theme styles and a functions.php file which included the parent style.css as below:


<?php
function theme_enqueue_styles() {
wp_enqueue_style( 'parent-style', get_template_directory_uri() . '/style.css' );
}
add_action( 'wp_enqueue_scripts', 'theme_enqueue_styles' );
?>

Now when I activated the child theme from Wordpress admin, changes in the child theme were not reflecting. I checked the browser source code and found that the child style.css was included before the parent style.css.
