Thank you for the quick response @saidaboukhadra but I am not using Elementor Pro. I am just creating a new page, while having Elementor and Starter Template installed. Then I select to edit my page with Elementor and, inside the paeg area, there is the Starter Templates widget, if I choose to import a template, or a block from Starter Templates, it doesn’t work and it gives this this error.
Thanks
