Hi @skyl,
There was a data loss with Alpha 1 a little more than a month ago. See this post for more details.
This explains why you are unable to access the SafeEditor website (http://safeeditor.davidmtl.safenet/).
I guess it makes sense to remove this link, since it doesn’t work anymore. I just removed it
For reports about apps.safenetwork.org, I would recommend opening issues on GitHub. But it’s completely fine to use this forum too (e.g. the Support category)
