Geeting blank page and errors on ionic2 update to 2.1.18

I have upgraded by ionic 2.1.17 to 2.1.18 using these commands:

npm uninstall ionic -g
npm uninstall cordova -g
npm cache clean
npm install cordova -g
npm install ionic -g
after that I installed a fresh ionic with sidemenus as :

ionic start --v2 test_project sidemenu
Now in test_project I replaced src of my original project (containing ionic 2.1.17)

currently I am having ionic 2.1.18…

The issue is that now I am getting only a Blank screen .

**** When i am hitting it in firefox it works fine but in chrome i am getting blank page.

In chrome console i am getting:

It looks like you’re using the disabled attribute with a reactive form directive. If you set disabled to true
when you set up this control in your component class, the disabled attribute will actually be set in the DOM for
you. We recommend using this approach to avoid ‘changed after checked’ errors.

form = new FormGroup({
first: new FormControl({value: ‘Nancy’, disabled: true}, Validators.required),
last: new FormControl(‘Drew’, Validators.required)

plugin.js:33 Native: tried calling StatusBar.styleDefault, but Cordova is not available. Make sure to include cordova.js or run in a device/simulator
** getting same error for android version greater than 5 also their also getting blank page on installing app.
