Basic description of the problem:
On iOS with WebView+, it shows "ERROR WARNING: CordovaLocalWebServer: tag src is not http://localhost[:port] (is index.html).".
Webview seems to work, but not WebView+
Framework/game engine (if relevant):
Construct 2, latest
I've use WebView+ a few months ago, and it worked fine.
I tried it with a blank game, with just a sprite; it still produces this error.
