Error event handlers for PhantomJS and CasperJS: PhantomJS and CasperJS don't show errors on the page by default. This can give clues as to what did go wrong.
var page = require('webpage').create(),
url = 'http://example.com/';
// Put the event handlers somewhere in the code before the action of
// interest (opening the page in question or clicking something)
// http://phantomjs.org/api/webpage/handler/on-console-message.html
page.onConsoleMessage = function(msg, lineNum, sourceId) {
console.log('CONSOLE: ' + msg + ' (from line #' + lineNum + ' in "' + sourceId + '")');
};
