Answer 1

Might be configuration issue.another possibility your current instance don't have SES permission. i am not very much sure it would be correct answer. but you can try it. @Create new AMI image of working instance with SES feature. and launch new instance from that AMI no. and check it.

Another possibilities are:

MYSQL and APACHE server should be in running mode.

For MYSQL Server:

/etc/init.d/mysqld status

if its not started then run

/etc/init.d/mysqld start

For Apache Server on Centos:

/etc/init.d/httpd status

if its not started then run

 /etc/init.d/httpd start
