Hi alism,
Many thanks for your continual assistance!!
I have resolved the problem by asking my web hosting service provider to restore the web contents to an earlier date. Frankly, up until now I have no clue where goes wrong. The website is blank even if I do a clean reinstallation of WordPress, very scary!
Once again, thanks for your help!
Regards

Thank you alism !

I have tried for the past hours but still could not restore the site. I have done a clean manual installation but the result is the same. Hmm… I regret upgrading. Any more helps would be greatly appreciated.

Of course my last resort is to rebuild the entire site by removing the existing database and wordpress !
