 * I am developing a wordpress plugin that connects to external database,
    fetch
   data, and displays it on metabox below page/post editor. I used following code:
 * /** MySQL hostname */
    define(‘EXT_DB_HOST’, ‘removed’);
 * /** MySQL database name */
    define(‘EXT_DB_NAME’, ‘removed’);
 * <?php
    /** MySQL database username */ define(‘EXT_DB_USER’, ‘removed’);
 * /** MySQL database password */
    define(‘EXT_DB_PASSWORD’, ”);
 * /** MySql table prefix */
    define(‘TABLE_PREFIX’,’removed’); $new_db=”; $new_wpdb
   =new WPDB(EXT_DB_USER, EXT_DB_PASSWORD, EXT_DB_NAME, EXT_DB_HOST); ?> saved this
   file as wp-db-config.php
 * included this file in constructor of main plugin class and
    I used ajax for fetching
   data. The data is shown in metabax below editor in both posts and page. I got
   success in adding, getting, deleting, updating data.
 * The main problem arise is that I cant update or create new post and page.
    I 
   googled this problem but I didnt get solution. Please help me out of this problem

 * Most likely the hook you are using. It’s probably running too early.. which is
   preventing the rest of the normal WP functionality to complete.
 * Use pastebin.com, and show me the code you are working with. Specifically, the
   code of how you are connecting to this database and displaying it’s contents.
