Hello,
Thanks for the reply.
1/ Make sure that you are using the latest versions of the theme and Core plugin – https://prnt.sc/201ao0a
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.
3/ Provide temporary wp-admin and FTP access, so we can take a closer look.
Regards
