I used the URL in Facebook’s Sharing Debugger and it gives me the following error message:
“Provided og:image, https://bolig.digna.eu/wp-content/uploads/2018/08/PRINT-NEW125.jpg could not be downloaded. This can happen due to several different reasons such as your server using unsupported content-encoding. The crawler accepts deflate and gzip content encodings.”
This is just an example. Facebook seems to have difficulty download the featured image in this theme, it has happened several times. Any ideas how to fix this?
