Can't get modpagespeed to work

[mehawk]

Hello again,

I am running CentOS 6.9 on Amazon aws. I have installed KloxoMR 7 on it with apache 2.4u-2.4.27-1 enabled. The problem is i have enable modpagespeed from KloxoMR panel but modpagespeed is not working. I have double checked list of apache modules and pagespeed.conf file yet modpagespeed is not working. modpagespeed log folder is empty i have check httpd logs for possible errors but found nothing. I have attached the result of sh /script/sysinfo.

Best Regards,
Mehroz Anjum.
