I have several WP sites that were logging in fine last week. Now today thay are all failing to login using the native wp-login.php.
The strange thing is some of the sites have the "Woocommerce" plugin installed, using the plugin login form I can access the dashboard. But not using wp-login.php
I have already tried:
adding this to wp-config.php
/** wp-admin login fix */ define('ADMIN_COOKIE_PATH', '/');
re-uploading all wp files apart from wp-content
Changing file permissions of wp-login.php
permalinks on and off
100% fresh install of WP 3.6.1 on a new DB
The thing that is confusing me is that I can still login using woocommerce on sites that have it. And the native login was working last week.
Could this be a hosting issue?
Any help / suggestions would be very much appreciated.
Thanks in advance
