Hello, I have same issue with importing Proto demo.
I’ve been using poro theme for more than than 3 years, but dunno what could be wrong. I’ve updated Porto to lates version 7.4. and update all related plugins. I followed procudure as described in https://www.portotheme.com/wordpress/porto/documentation/update-theme/. After updating Elementor to the newest version page was broken. Then I revert Elementor to previous version. I wanted to import “demo Shop 49” but got the same error messsages eventho my server meets all requirements.
