Hello Web Lab,
Thank you for contacting us and for using XStore.
1/ In order to troubleshoot issues you are experiencing, we suggest that you first try disabling all third-party plugins (including cache plugins) that are not bundled with XStore. You can refer to the following link for a list of included plugins: https://www.8theme.com/documentation/xstore/plugins/included-plugins/ . Additionally, please clear the cache of your browser and check again. It is possible that one of the additional plugins is causing problems.
2/ Make sure that the problem is not caused by changes in theme files.
3/ Please follow this article also – https://elementor.com/help/troubleshooting-a-slow-loading-elementor-editor/
Kind Regards,
8theme team
