Can't reproduce with vanilla 1.8.3 with the Blog theme, despite changing it to have a {% render_section "Header", required: true %}.

Note that this exception is thrown if you try to render the zone with {% render_section "Header", required: true %} but the zone is empty, i.e. it doesn't have any shapes or widgets. If you want to allow empty zones, you need to render it with {% render_section "Header", required: false %}.

What do you have in your code, and what doesn't match your expectations?

Hi @Piedone,
Yes, I have changed it to have '{% render_section "Header", required: true %}' and there's a test html widget in Header Zone.

At first, it was normal, but after I deleted the Header，Footer zone, saved it, and then re-added the Header,Footer zone and added widgets to these zone, then the error occurred.

Can't reproduce with a widget either (having a widget in the zone causes this exception not be thrown anyway).

Please provide a screen recording of you reproducing this, starting from an empty app, and showing the whole browser window.

Thank you for the details! However, I still can't reproduce with vanilla 1.8.3 (nor do I see how this can happen with the 1.8.3 code). Could you try to reproduce it with a vanilla 1.8.3 as well, including the changes you make to e.g. the Blog theme? Or share the full solution with us, including not just the source but the DB.

I deleted the site and reinstalled it, and all the issues was resolved. Thanks.
