The 403 error is likely due to server permissions preventing access to the required AJAX call, so troubleshoot server settings and plugin conflicts.
When debugging the checkout process, check for JavaScript issues that might prevent the loading of necessary components, such as jQuery scripts.
Deactivating and reactivating plugins can help identify conflicts that may cause the spinner issue, alongside reviewing the console for errors.
Ensure that the WooCommerce settings are correctly configured and that AJAX is functioning properly in your WordPress installation.
