But this is what I used to have
Do you know of a way to fix this?
Thanks
The screenshots look like you used to have a writer field in there — not the markdown editor. The default text block uses a writer field, as you can see here: text | Kirby CMS
This should be enough to render the HTML with the writer field:
type: blocks
fieldsets:
- text
You might have to change the type of existing blocks.
