Domain not loading as expected

Hello,

I hoping you can help me out. I have not long ago setup dns for google pagespeed, my problem is my website works perfectly fine, it loads, shows every icon etc but if i setup the domain as (without /www) mydomain.com but it don't show well if i set it up as /www.mydomain.com it doesn't load the search and some icons are missing so it doesn't completely load the template if that makes seance. I am using a vps with cPanel/WHM, and my website is running wordpress, here a screen shot

any help would be appreciated

I am currently using Google page speed DNS to obviously speed the website but it works completely fine if the domain is set in general settings as (without /www) mydomain.com , it works completely fine everything loads, but if the domain is set as /www.mydomain.com it wont search for anything or show anything under the categories it just spins & spins nothing loads, the website is still fine it still shows the template but it just wont show any listings it just keeps spinning (loading). Any suggestions? Thank you Regards.

 

Ignore all the writing after the "any help would be appreciated"... the screenshot i blanked stuff out because i dont know if its sensitive information.

 

sorry late reply.
I am not really sure what to say because the theme does load but not all content but if the domain is set too http://mydomain.com it will load all content.
