. I disabled the LiteMage cache, CDN and tried it again. Also, I tried with default Magento checkout by disabling the extension. It is also not working in the sites. I checked logs and found is_AJAX variable issue in the default Magento checkout and tried to solve it with core code updates. It is not working so, I reverted it back. No other errors found in the logs. Also, I am unable to see any IWD extension error in the logs except the browser console. Regarding the browser console error, it looks JS library conflict issue and I am unable to solve based on the knowledge.
