I tried to download the latest daily build (2843) today. When I went to the daily build page ( http://developer.coronalabs.com/downloads/daily-builds ) I couldn’t find the plugins.
After an hour WASTED to search what is wrong with this website, I found something interesting.
If you go to the https version of the same page ( https://developer.coronalabs.com/downloads/daily-builds ), plugins are here and available for download.
This was quite annoying honestly, please be careful with those kind of thing, as the “daily builds” button on the website redirects on the http page.
