Social Sharing Preview Problem

Hi everyone,

I’m facing an issue with sharing my project on social media. Specifically, I’m encountering two main problems:

  1. Readymag is generating a grey image, instead of using the page’s screenshot as the preview image. The grey image is not visible either while sharing, it’s only in the Sharing settings.

  2. When I upload a custom preview image, it doesn’t display.

The Facebook Debugger also shows this error:

‘URL returned a bad HTTP response code.’

This project is published on Readymag and isn’t connected to any domain.

I’ve reached out to Readymag support back in August and followed up last week, but they haven’t found a solution yet. Their tech team hasn’t looked into the bug either.

Has anyone else experienced similar issues—particularly with missing previews and bad HTTP response codes? Any suggestions on how to resolve this?

Thanks in advance!

Can you share more details? What’s your website’s link? Do you get that on every social platform?
