When I cloned https://blocks.wp.a2z/block_example/cover-block-with-parallax/ to https://blocks.wp-a2z.org/block_example/cover-block-with-parallax/ the background image
was not displayed on the target.
The background image in the source was WordPress-paper-chain-scaled.jpg
When I cloned
https://blocks.wp.a2z/block_example/cover-block-with-parallax/
tohttps://blocks.wp-a2z.org/block_example/cover-block-with-parallax/
the background image was not displayed on the target.The background image in the source was
WordPress-paper-chain-scaled.jpg
When this attachment was cloned on 24 Nov 2020 the target file became
`WordPress-paper-chain-scaled-1.jpg
During the clone there was no change to the filename so on the target site the background image was missing.
Workaround
I renamed the target file in the server.
Attempt at a better workaround
