Hi brianrivet,
I’m so sorry that happened! Let’s see if we can get it overridden. Open /system/expressionengine/config/config.php You should find a blank line around line 24 place this code there:
$config['cookie_domain'] = "";That will override the value you have set in the Control Panel. Once you are able to login, you can unset the value in the CP, and then remove this line from confg.php
