1,2/ We recommend that you disable all third-party plugins that are not included with XStore
(https://www.8theme.com/documentation/xstore/plugins/included-plugins/). After doing so, please clear your browser’s cache and check again. It is possible that one of these additional plugins is causing the problem.
3/ https://gyazo.com/2ed5dede9dbb8227a4e9ac5e7b2d4a9a There is no such option, unfortunately.
Best Regards,
8Theme’s Team
