Just a heads up for anyone who can't login even if you reset the password on a new duplication of wordpress.
If you have use a cache plugin, CHECK for the 'Cache' lines at the top of wp-config.php
Check that the new address is correct. Solved my problem after 3 hours of looking!
define('WP_CACHE', true); //Added by WP-Cache Manager define( 'WPCACHEHOME', 'public_html/XXXX/wp-content/plugins/wp-super-cache/' ); //Added by WP-Cache Manager define('COOKIE_DOMAIN', 'XXXXX.Domain.com.au'); // Added by W3 Total Cache
Yeh I did experiment with a few caching programs!
