Restoring a Team site which contains Apps, web parts, script will show a white blank page

I have a team site collection inside my development machine, which contains :-

1. One document management APP.
2. One announcing APP.
3. 5 overlay calendars
4. 1 content editor web part.
5. 1 script editor web part.
6. App part for displaying the document managemt, announcement and the overlayed calenders        

I have back-uped the site collection on ym development machine, then I have restored it to my staging machine. But when I tried to access the site collecting on my staging it will show an empty blank white page.Baring in mind that I have a community site which contains a discussion forum, and the restore went sussfully without any problems. Can anyone advice on what might be the problems?
