Let’s try this,
Open up your wp-login.php file and add the following update_option calls,
update_option('siteurl', 'http://your.domain.name/the/path' );
update_option('home', 'http://your.domain.name/the/path' );
beneath,
require( dirname(__FILE__) . '/wp-load.php' );
so… it should look like,
require( dirname(__FILE__) . '/wp-load.php' );
update_option('siteurl', 'http://www.example.com/' );
update_option('home', 'http://www.example.com/' );
Where http://www.example.com/ should match your domain.
- Then visit your login page.
- Then remove the lines added to
wp-login.php
You might need to refresh your login page a couple of times or try and login a couple of times but it should let you in. Might be neccessary to clear your cache.
If all of a sudden,
http://www.example.com/
was appearing like,
http://example.com/ (no www - for example sake)
…then it might be causing this redirect loop issue you are having. Its easy to miss a slight change like that in your login URL as we often are not paying that close of attention.
So by running the update_option above we reset those paths to their original format.
IF its not the above then make sure you definitely PURGE all of your browser cookies because there is a mismatch somewhere that’s causing the issue. Has to be.
