Hello,
1/ FTP directory is empty. Provide us with FTP to your WP installation.
2/ Try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://xstore.helpscoutdocs.com/article/36-included-plugins , clear cache of browser, and check then. Maybe one of the additional plugins is a reason for the problem. Let us know the result.
Regards
