Hello, Mirza Ahtsham,
Thank you for choosing XStore as your WooCommerce WordPress theme.
Regarding the issue you are experiencing with the form on your website’s front page, the error message suggests there may be a server-related problem. In such cases, we recommend reaching out to your hosting provider first, as they can check for any server-side issues and are most likely able to resolve them.
If you need any further assistance, please feel free to contact us.
Best Regards,
8Theme’s Team
