Saying "randon issue" is not enough information to help you. Currently in Magento admin there is no backbone.js. Could it be you customization? Also it will be handy:

• Do you setup CORS for CDN server?
• What we are talking about?
• What browser console says?
• If you use some custom JS on this page? What is? Could you point to sources?

sure i am putting my apology for not clearing it in details .

1 - what we did we setup a magento2 instance in our aws server in this manner http://m2.example.com/m2

2 - and this url works under the cloudflare as DNS propagation takes place from the CDN server

3 - we did not change anything its a fresh magetno2 setup

4 - when we tried to open the catalog product grid it shows blank and when i hope the console(Firefox , chrome ) to check the issues we got the knockoutjs error i am sorry i wrote it wrong

5 - when we remove the cloudflare from the subdomain everything works great

i hope i explained it well this time .

@webkul do you have Railgun or Javascript optimisation enabled on Cloudflare? It does have some options that mess around in JS/CSS files served.

With CloudFlare CDN enabled, I had a problem with the customer and product grids not loading, even though the AJAX call was returning populated with data. This also happened with the cart on the storefront. I solved this issue and everything is working perfectly now by turning off the Auto Minify feature for JS and HTML. If you look at the source of the HTML fragments that get loaded after the XHR response is complete, there is logic embedded within comments. These are stripped by Auto Minify. This embedded logic in comments is for knockoutjs, to declare templates for layouts.

Hi Suzanne, Its a good notice about CloudFlare and its AutoMinify feature. Thanks for this notice.

Under internal ticket MAGETWO-50525 will investigate possible solutions from Magento app side.

Magento 2.0.2 EE products and customers grids are empty when CloudFlare Rocket Loader enabled, after disable and leave only CDN features - works fine.

I set up MAXCDN with Magneto2 using the following settings and it seems to work well.

Make sure you clear all caches after you make the changes. I am getting about 70% hit rate. The CORS seemed to help with the static files.
