500 Internal Server Error (Wordpress 4.9 >)
===========================================
Description: This error was caused when i deployed wordpress from local to live hosting.

1) First check the .htaccess file

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


To:
----------
# BEGIN WordPress
RewriteEngine On
RewriteBase /
RewriteRule ^index.php$ – [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

# END WordPress





2) Now i check the wp-config.php file


Change from:
-----------
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/wordpress');
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] . '/wordpress');

To:
------
define('WP_SITEURL', 'http://' . $_SERVER['HTTP_HOST'] );
define('WP_HOME', 'http://' . $_SERVER['HTTP_HOST'] );



3) Check the database parameters in wp-config.php file and correct them.

/** The name of the database for WordPress */
define('DB_NAME', 'bitnami_wordpress');

/** MySQL database username */
define('DB_USER', 'bn_wordpress');

/** MySQL database password */
define('DB_PASSWORD', '');
