Hello

Onebox goes well on my discourse forums, but links from one of my sites don’t display in onebox.

Example :  
`https://www.wikibulles.org/sos-ici-paris/302-3884-4596/302-27-0-0`

I tested with 2 discourse forums, and now on this meta forum.  
The target page contain meta tags in header, with all required og: tags.

Debug with [https://developers.facebook.com/tools/debug/og/object/](https://developers.facebook.com/tools/debug/og/object/)  
and [Iframely URL Debugger - Open Graph, Twitter Cards, oEmbed](http://iframely.com/debug) displays no error.

What info missing ?  
An idea ?

Debug or logs about onebox available somewhere ?

Thanks

It has no text description therefore it cannot be oneboxed. It must have a text description.

Now with description, onebox is created.  
But no title and no image. Tags og:title and og:image are here !  
I added also og:image:secure\_url and og:image:alt

What’s the problem now ?

It would be usefull to know exactly what onebox want…

In another site, I created this tags, and onebox runs well…  
Title and image tags are here, and it works. Above, title and image tags are here so, and it don’t works…  
I don’t undestand…

Image was not displayed in ondebox when I had the header  
`<link rel="canonical" href="https://www.wikibulles.org/n12-2e-semestre-reliure-coeurs-vaillants-1952-reliures-c339urs-vaillants/75-29-29" />`  
I removed this line, it’s OK.

Now I have to know if this line is needed, ie for social network…
