New project OpenFl > HTML5 under FlashDevelop

Hello everyone, I did not know where to place my concern, so I placed it here.
When I start a new openfl project targeting HTML5 (it is the default), I have this error before doing anything:

Error: "project.xml" is an unknown target

I look at this file, but can’t even find the word “Target” …
Any idea guys?

You might have an application.xml instead. Try rename it project.xml.

Also instead of Flash Develop. Use Haxe Develop. Go to new >> create an empty haxe project. That will set it up all automatically.
