Wordpress REST API (wp-api) 404 Error

Question

I have been using the Wordpress REST plugin WP-API for months now while developing locally with XAMPP. I recently migrated my site to an EC2 instance and everything is working fine except I now get a 404 with the following message whenever I try to access any endpoint on the API:

The requested URL /wordpress/wp-json/ was not found on this server

Pretty permalinks are enabled with the following structure http://.../wordpress/sample-post/ which works fine when navigating to a specific post in the browser.

Here are some details about my setup:

• Wordpress 4.4.1
  • Not a Multisite
• WP REST API plugin 2.0-beta9
• Apache 2.2.22
• Ubuntu 12.04.5

Any help would be greatly appreciated as I have gone through SO and the WP Support forums for several hours and am out of ideas. Thank you!

Answer 1

I had moved the WordPress install from a subdirectory to another, so in my case the problem was due to the WordPress config in the .htaccess files. It was trying to redirect every page but the homepage to the old directory. It was just a matter of updating olddir to newdir... This tripped me up more than once so I thought I'd put it here...

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /olddir/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /olddir/index.php [L]
</IfModule>

# END WordPress

Answer 2

I had to manually make a .htaccess, set it to chmod 664, and copy the permalink rules into it.

I also played around with

• Settings > Permalinks
• Manually updating .htaccess via the code at the bottom of the permalinks page after clicked "Save"
• Adding "index.php" as one of the other answers suggests
• Making sure mod rewrite was enabled via a2enmod

Answer 3

I solved this issue through following steps:

1. Navigate to ..\Apache24\conf\httpd.conf and search for LoadModule rewrite_module modules/mod_rewrite.so.

2. Enable rewrite module by removing the # mark.

3. Replace all the cases of AllowOverride None to AllowOverride All.

4. Don't forget to restart apache server. :)

Answer 4

It turned out to be a problem with the Apache configuration.

First, I deleted the .htaccess file in the root wordpress directory.

Next, I navigated to /etc/apache2/sites-enabled and opened 000-default

All of the AllowOverride variables were set to None, which I replaced with All.

That did the trick!

Answer 5

UPDATED NEW WAY

I also faced similar problem in a local project. I used index.php after my project url and it worked.

http://localhost/myproject/index.php/wp-json/wp/v2/posts

If it displays a 404 error then update permalinks first (see "Paged Navigation Doesn't Work" section

If it works, maybe you need to enable mod_rewrite, on ubuntu:

a2enmod rewrite
sudo service apache2 restart

Installation

The REST API is included in WordPress 4.7! Plugins are no longer required, just install the latest version of WordPress and you're ready to go.

If you're before 4.7:

1. Download plugin from here: http://v2.wp-api.org/

2. install and activate it.

Usage

To get all posts:

www.mysite.com/wp-json/wp/v2/posts

For the search functionality, searching for test post looks like this:

/wp-json/wp/v2/posts?filter[s]=test

Answer 6

On WPEngine and WP 4.9.2 I only had to update permalinks to get fresh, newly installed site to return v2 API calls. What I did:

1. Create site
2. Browse to http://yoursitename.wpengine.com/wp-json/wp/v2/posts
   • get 404
3. Go to admin, settings, permalinks, choose "Post Name"
4. Click "Save Changes"
5. Browse to http://yoursitename.wpengine.com/wp-json/wp/v2/posts
   • success. page displays JSON response
