Hi everyone,

I just changed mysql password of db user (in wp-config file)
I tried with both ways: admin tool, sql command with PASSWORD('mypassword')
then after that my wp doesnt work anymore. It said as the following quote
So what is the problem and how can i fix it?
Thank you.

 * Front to the WordPress application. This file doesn't do anything, but loads
 * wp-blog-header.php which does and tells WordPress to load the theme.
 * @package WordPress

 * Tells WordPress to load the WordPress theme and output it.
 * @var bool
define('WP_USE_THEMES', true);

/** Loads the WordPress Environment and Template */
require( dirname( __FILE__ ) . '/wp-blog-header.php' );
  • This is unlikely to have been caused by changing the database password. When WordPress can not connect to the database, it simply shows:

    Error establishing a database connection

    This seems to be your webserver not executing PHP. Did you happen to make any changes elsewhere at the same time? Are you using Apache? Nginx?

  • yah, you might be right.
    I installed mod_security and it might change the config file
    php module is still ok but PHP is not executing.
    Cant find the root cause now... Im using Apache!
