My brother in law has a simple website for his small business, and he has requested I change the image for the embed when the site is shared on facebook. Everything looked fine when I checked it with an Open Graph preview, and sent a link via messenger but the embed will not update on facebook itself, even after using the sharing debugger.

Meta Sharing Debugger keeps trying to point to the logo image, so I tried changing the filename for that and it instead just defaulted to a random image on the index webpage instead.

The website is hosted on Netlify.

As shown here, this is how the website should look, but Facebook does not seem to agree:
Open Graph Validation

I changed the og:image url to point to the new image, then ran sharing debugger for facebook to clear the cache, which doesn’t seem to have worked. I also tried clicking the 3 dots next to an already shared embed and clicking “refresh shared content” which also did not work, it still uses the logo.

I’ve tried the following solutions found on stackoverflow:

1. jquery to refresh it but I get this error: Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://graph.facebook.com/. (Reason: CORS request did not succeed). Status code: (null).
2. fbrefresh URL parameter also did nothing.
3. Also tried doing it using a php script but my knowledge in that department is limited so I am not sure why it didn’t work, console threw no errors.
