Hello, Valeri,
Thank you for contacting us and for using XStore.

Try to disable all 3rd party plugins, maybe one of them is the reason for the problem with Elementor for static blocks.
If this doesn’t help, please provide temporary wp-admin access, so we can check your settings.
To provide wp-admin access, you can create a new user account with administrator role via the Dashboard, and provide us with the username and password via the Private Content area.
Kind Regards,
8theme team
