Multiple ThemeGrill Block Errors

I installed the Accelerate theme and receive multiple block errors on Widgets page. All plugins are inactivated. If I activate “Classic Widgets” then I don’t get the errors but I’m not able to use the TG Featured Widget or the TG Image Services because I can’t select any images (there is no option to select images.

This is a new WP install with the latest version. 1st action was use the demo installer. Here are the errors I receive:
