Error while using ajax search in component selectionn

Hi Team,

We have observed a peculiar error on our pc build page (https://www.pcstudio.in/pc-build/). Request you to kindly help us on fixing the same as this page is the most visited page of our website and we always have high traffic on this page.

Issue:

When user selects components (adds to the build) from the ajax search of the component selection page and clicks on add to build or select then a blank screen is shown with a ‘0’ and the URL is admin ajax php.

Do let me know if you need any other information.
