It seems that some sort of login loop has been created in my Wordpress environment. I've tried everything, but can't figure out what's causing it. The only way I can get in is to rename the plugins folder and/or disable all plugins. It seems the one causing the issue is "Domain Mapping". However, I just did a network uninstall on that plugin and removed the "Sunrise" items it had me do on the wp-config and sunrise.php file and I can no longer login under any situation (plugins or not).
Might anybody be able to lend a hand and/or point me in the right direction?
