Hello, Subho,
Thank you for reaching out to us. We understand that the header on your website is displaying twice.
We suggest disabling all third-party plugins (including cache plugins and disable CDN on your site) that do not come bundled with XStore (https://www.8theme.com/documentation/xstore/plugins/included-plugins/ ). After that, clear the cache of the browser, and then check the result. It is possible that one of the additional plugins is causing the issue.
If this doesn’t help, provide us with temporary FTP access.
For FTP access, we require the following details: FTP host, FTP username, FTP password, FTP port, and FTP encryption type. If you need assistance in creating these credentials, please reach out to your hosting provider who will guide you through the process.
Warm Regards,
The 8Theme Team
