Hello,
Thanks for using our theme.
Try to disable all the third-party plugins (including cache plugins), that do not come bundled with XStore https://www.8theme.com/documentation/xstore/plugins/included-plugins/ , clear cache of your browser, and check how it works then.
If these issues are not caused by additional plugins, provide temporary wp-admin and FTP access, so we can take a closer look.
Regards
