Yikes. I accidentally created an infinite loop with a global asterisk field for the entire domain to forward to the index.php. Which meant I couldn't access the WP Admin tool - it kept forwarding to the root index.php. I deleted the 301 simple redirect plugin folder via FTP, which solved the problem. But when I went to re-install the 301 simple redirect plugin, the infinite loop returned.
How can I wipe out the simple 301 redirects and start over completely?
