Hi Sir, The is the error of 1st https://prntscr.com/qgnf7o After the 1st Debugging by disabling the CORS, https://prntscr.com/qgndjx Is the 1st debugging an improper action? What should I do the get the app display properly on the browser?

The CORS are most likely returned in response. If you’re using caching plugin w3tc then make sure it is not adding any .htaccess code to remove cors. On many sites using w3tc we found this issue. I will need admin credentials to further debug this.

Hi, The issue is caused by third-party plugin. Your app already working please deactivate plugin: WooCommerce Blocks. Then try to run your app. Refer this image of working app from your site:http://prntscr.com/qhhcqw Same thing you have to do for your local setup. For build update your config.xml like this http://prntscr.com/qhsegc code:   <access origin="*" />
