NEW Warning Errors!

Can’t get logged into admin, get this warning:

Warning: Cannot modify header information – headers already sent by (output started at /xxx/xx/xx/xxx/xxx/wp-content/plugins/accelerated-mobile-pages/templates/features.php:320) in /xxx/xx/xx/xxx/xxx/wp-includes/pluggable.php on line 1174

🙂 Had to go into FTP, rename your AMP plugin folder, just to log back in. 🙁
Please help!
