subdomain of wordpress keep redirecting to main domain

this is what I did and expect to clone a wp blog for development.

  1. I created a sub domain in cpanel, says dev.myblog.com
  2. I download a copy of db and then uploaded to the newly created db.
  3. I changed the wp-config – db name etc..

but the problem is the sub domain keep redirecting to the main domain

  1. To create you should

    1. export DB

    2. change the URLs in db file

      1. open db file using Wordpad or any editor

      2. find wp_options

      3. then scroll down little bit, you find your old URL

      4. replace the old URL to new URL in complete file

      5. save the file.

    3. import the file to the new DB

    4. now run the new URL in browser

    Note: after this you must add the widget data and also update the permalinks

  2. You need to update the site URL and home URL in your database (wp_options table). You’ll probably want to replace other mentions of your old URL too, such as in linked posts or the guid.

    You say you use cPanel, so you should have access to phpMyAdmin. If you go there, you can run this SQL (you’ll need to replace the old and new URLs where appropriate):

    UPDATE wp_options SET option_value = replace(option_value, 'http://www.oldurl', 'http://www.newurl');
    
    UPDATE wp_posts SET guid = replace(guid, 'http://www.oldurl','http://www.newurl');
    
    UPDATE wp_posts SET post_content = replace(post_content, 'http://www.oldurl', 'http://www.newurl');
    
    UPDATE wp_postmeta SET meta_value = replace(meta_value,'http://www.oldurl','http://www.newurl');
    
  3. Change the site URL on the WP_OPTIONS table if it exists on DB if not
    go to wp-config.php and add below two entries on the file.

    define('WP_HOME','http://subdomain.example.com');
    define('WP_SITEURL','http://subdomain.example.com');
    
  4. In order for this to work for me I first added the following to wp-config on the sub-domain:

    define('WP_HOME','http://subdomain.example.com');
    define('WP_SITEURL','http://subdomain.example.com');
    

    The above still forwarded to the main site so I then opened the sub-domain’s DB in phpMyadmin and updated the site URL under wp-options.

    Once I did that it was forwarding correctly.
