[WinmezzZ]

webpack Dev Server Invalid Options

options should NOT have additional properties

Same problem here, whats the fix ?

Edit: I don't have this error message with 1.0.0 version, but i don't have any overlay either with an error. And no specific error in the console for this plugin.

Is this package compatible with Webpack 4? I have the same issue.
If it is not compatible would be nice to mention in the README and remove Webpack 4 from peerDependencies.
