Can’t even get it to activate!

Fatal error: Cannot redeclare amp_force_query_var_value() (previously declared in /home/manches9/public_html/wp-content/plugins/accelerated-mobile-pages/includes/vendor/amp/amp.php:16) in /home/manches9/public_html/wp-content/plugins/amp/amp.php on line 74

Not a great start! Doesn’t fill me with confidence that it’ll work, but hopefully support can resolve the issue and I can improve my review rating.
