0. The third day still has no solution for it. It is time to do something big.

1.Get hint from internet, tell me find the back uped database, could be corrupted.

2. Go central management, try server back up, failed, get multiple recommmandation to upgrade databse.

3.  Go to management shell, Run PSConfig.exe -cmd upgrade -inplace b2b -force -cmd applicationcontent -install -cmd installfeatures.

4. Recall I have tried to upgrade server to Enterprise but I don`t have Enterpise Certificate, and it was stopped halfway, could be related.

5. go to site permission again, problem still there.

6. So I have to back up whole website and prepare to start again.

7. The most important part is my subsite, so i use those backup and restore->Granular Back up->export a site or list to back up my subsite first.

or.

stsadm -help export

[stsadm -o export -url URL -f filename]

stsadm -help import

[stsadm -o import -url URL -includesecurity]

8. I have also backed up my customized templates.

9. Now I need back up several pages I have done manually.->9:18 AM

10.9:32 delete site.

11. Uninstall sharepoint 2010. Retart.

12. ReInstall 10:06Am.

13. reinstalled 10:45AM.

14. Restored coreV4.css and v4.master. the Problem reappeared. Change back the v4.master, problem disappeared. So it is the V4. Master!!!

15. Problem Solved. Now I need to restore the whole site!!!

16. Go to sitecollection, open publish feature for site collection and site.

17. Go to general settings of application management, change person name actions to no, browser file handling to permissive, recycle bin to off. ok.

18. Go to manage Farm Features->deactive social tags and Note Board Ribbon Controls Feature.

19. Central Administration->Security->Autentication Providers->Default->Edit Autentication->Enable Anonymous access. Save.

20. copy v4.master and rename it. Design again.

21. import the subsite I backuped->11:18Am

22. Change maximumDynamic DisplayLevels=”5″; under new master template.

23. Change Corev4.css to customize my menus

white-space:nowrap;

font-weight:normal;
