I've been embedding student projects on a weebly site for the past two weeks. Up until now it's been working fine. But today, suddenly all of the scratch projects load to a blank screen when you click the green flag. I went to different sites that scratch listed as examples of websites that have embedded projects and I can't watch theirs either. Did something happen with the Share to button? Can we no longer embed onto other sites? I'm freaking out here! I have 55 students that have worked really hard to exhibit their projects on a Periodic Table website and now nothing works. Help!

Have a similar problem – my entire class uploaded their projects to the site then got the embed code loaded it into their Google SItes ePortfolios –
had issues with the ssl script - fixed that but still no projects appearing ! Same kind of frustrations for the students.

your not the only one; ive got a big presentation coming up involving weebly and scratch games and then today i get a blank screen!
hopefully there is a solution to this.

Probably better off reporting in Bugs or questions about Scratch?

Actually, I know what's wrong. If I try to embed my bubble blaster project, It won't work. The code is below.

<iframe allowtransparency=“true” width=“485” height=“402” src=“//scratch.mit.edu/projects/embed/43907246/?autostart=false” frameborder=“0” allowfullscreen></iframe>

The reason this dosn't work is because the code is missing https: is the src. Here's what the code should look like.

<iframe allowtransparency=“true” width=“485” height=“402” src="https://scratch.mit.edu/projects/embed/43907246/?autostart=false“ frameborder=”0" allowfullscreen></iframe>

Notice the new https.
