When did they remove this? The settings are still available in the media settings?

On the new version (3.5) they removed the oEmbed settings

Ah – you mean this: ‘Remove oEmbed options from the Settings Media Screen. Width adheres to theme’s content width, height is 1.5 times width’.

Shouldn’t make any difference really – actually should be better. But I will investigate to see if we can add some CSS to give it some right hand margin on forum posts.

Ok, let me know if there’s anything I can try in the meantime

You could try something like this – try adding it to WP theme CSS or even the forum theme CSS:

#spMainContainer embed,
#spMainContainer iframe,
#spMainContainer object,
#spMainContainer video {
    max-width: 95%;
}

See if that helps at all…

I added this to the default.php, worked like a charm!

.spPostContent p iframe { max-width: 100%; }

Which is rather strange as you can’t put an iframe in a paragraph and a max of 100% is exactly what WP already set it to! So it shouldn’t really make any difference!

I guess it takes the 100% of the spPostContent

I have to say I have never heard of it and I don’t recall that name ever coming up on the support forum. How does it work? And what does it do?

Oh, I just deleted the comment because I figured out what was wrong with Embedly

Anyway I’ll tell you in case you’re interested… It’s a WP plugin that allows you to embed almost everything, from brightcove videos to bandcamp playlists. It’s free if you make less than 10K requests a month

Ok – so does that mean you now have it working? It sounds interesring.
