Hello,
Instagram made some changes in their code, so we did changes in our theme – https://xstore.8theme.com/update-history/ http://prntscr.com/p60kjo
To use Instagram on the site, you need to update XStore theme http://xstore.helpscoutdocs.com/article/63-theme-update and Core plugin https://xstore.helpscoutdocs.com/article/37-plugins-update
Please note that any Core plugin update requires the theme update to the latest version before the plugin update. 6.0 was a major update, Redux Framework was changed to Kirki. Do the backup of all the files and DB before the theme update.
Regards
