LL (0.4.0) stopped working for iframe content for some reason – the only change i made to this content was to wrap it in a div – here’s some sample code:
If you remove the .embed-container div, does it still work?
How are you adding the embed-container? Are you manually coding it straight into the content field of the post/page? Or are you using some sort of shortcode/plugin to generate the div with the video inside it?
I released a patch today that fixes this issue, plus a few others. You should see an update available for it in the admin. I don’t think you’ll need to reinstall it (although, to be honest, I’ve never tested that theory).
Let me know how it goes. Also, I’ve got a donation page set up, but that’s certainly not necessary.
