• WordPress REST API point (wp-api) shows 404 error. It can be checked by accessing http://example.com/wp-json/wp/v2/posts

3.Create the .htaccess file by clicking on it or edit existing .htaccess and add below lines:

# BEGIN WordPress
# The directives (lines) between "BEGIN WordPress" and "END WordPress" are
# dynamically generated, and should only be modified via WordPress filters.
# Any changes to the directives between these markers will be overwritten.
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# dynamically generated, and should only be modified via WordPress filters.
