Issue with validating the code

I had purchased this theme and validated earlier on nepalesefoodlovers.com website. For some reason my website had lots of issues and therefore uninstalled it and re-installed wordpress. now when i am trying to validate the webiste it says invalid code.

Now iat the same time, i would like to know, how can i simultaneously work on two live site. One as a demo or clone for updates and experiment before i actually integrate it on final live site. If i wish to work on local server in PC which code should i use. I want to use in on local server demo site and live demo clone site before implementing the changes on main site. How can this be done.

Please advise.

Also one last question: while designing a page, can i use cornerstone and visual composer both at the same time or will i be able to use only one plugin do design particular page. Asking because earlier when i designed the page i could so either cornerstoe designed page or visual composure designed page.

While registering a product i also get a message

Hi Pramod,

We can use each license for one production and staging site only. We can set each URL on our licenses page.

About page builder, we can use one page builder per specific page. When a page is built using Cornerstone from the start, we can’t edit it using other builder like visual composer and vice versa. We can only use Cornerstone for editing it’s content if it’s created using Cornerstone, and Visual composer if it is originally created with visual composer.

Regarding the issue with the purchase code, please share the purchase code with us use using a secure note so we can double check.
