Related to that changes, there is a syntax error in the logs due to a
Uxpected 'define' (T_STRING) in /opt/bitnami/apps/wordpress/htdocs/wp-config.php on line 24'
The following snippet is the diff between the original configuration and your configuration:
< define('COOKIE_DOMAIN', $_SERVER['HTTP_HOST']);
< define('FORCE_SSL_ADMIN', true);
< define( 'DOMAIN_CURRENT_SITE', 'lizardgizzards.com' );
> define( 'DOMAIN_CURRENT_SITE', 'ip-10-10-97-170' );
It seems to be something wrong there.
Apart from that, I can see only errors with PageSpeed. PageSpeed usually fails with small instances, in any case could you try to disable it?
