Error Sending Project to Gallery

Hi, I'm having trouble publishing my project to the gallery. Everytime I click Publish to Gallery, I keep getting the same error message: "Error sending project to the Gallery." Anyone know a way to fix this?

Thanks!

Have you used extensions? Because if so, you won’t be able to upload apps to it.

No I haven't.

Well that’s me out of ideas, sorry.

No worries. Is there a way to duplicate a project so I can try to publish that instead?

You can Save project as ...

saveProjecas

Exactly what I needed to know and they didn't mention that at their doc easily or I would have found that!

that does not work for me
