Just made a small change to a nicely working global block - I increased a gap from 1em to 2em, saved it, and the whole section, with the row and two columns it contains, is suddenly invisible in the design/previeiw in the global block editor, and on the resulting website. All the components are still there.
Do you have any idea what might have happened, and how I might be able to recover the block?
The reason for the change was that I need to find a way to move from earlier from a 2-column-layout to a one-column-layout then the editor allows directly. I guess I would need custom CSS, where and what would I have to add?
Thanks, and best regards
