This link is not “oneboxing” on my site– [图片] Michael Flynn's case ordered dismissed after appeals court overrules judge The surprise ruling came as the trial judge had questioned the DOJ's move. Hmmm and I see it isn’t here either. Yet ABC News has (unsurpr…

The two usual culprits are missing open graph tags, or something either blocking the Discourse UA or cloud provider IP ranges. Just because we can see the tags locally in our browser doesn’t mean the server necessarily can. A bit of tinkering in cURL from your VPS will usually identify the cause.

Use the iframely tool to troubleshoot the opengraph / oembed tags in the page. Lacking a text description of any kind is another reason I sometimes see in the wild.

Hmmm ok. I think I might have figured it out… it is a missing “description” field, perhaps? Here are 3 links from big sites and the related iframely reports. [图片] Michael Flynn's case ordered dismissed after appeals court overrules judge The surprise ruling came as the trial judge had …

[图片] pnoeric: Could any of those be “showstoppers” that prevent onebox from kicking in? Yes, no description means no onebox.

Oh. :-/ That seems like… a dramatic step. I don’t see why all the beautiful grace of the onebox should be discarded if just a description is missing. I’ll try to do a PR that allows sites that don’t have a description field (so far, we have found that ABC and CNN are two of them) to still let the i…

I wonder if we should just remove the “description required” rule and make it optional at the site setting level: [image] The onebox on the OP is pretty reasonable imo, the description feels unnecessary.

[图片] pnoeric: Glad that Discourse can follow suit. This is premature. This may or may not happen, @codinghorror is the PM and gets to choose the implementation we go with. I think that the no description, no onebox rule should be lifted and be an opt-in thing if we must, but ultimately this …

Fair enough. It does seem weird to me that if the choices are: OPTION A - current behavior if no description available Hey, check out this article: https://www.nbcnews.com/politics/congress/cats-saved-gov-t-kitten-slaughterhouse-visit-capitol-purr-thank-n1034811 OPTION B - (suggested change) d…
