Can't find taxonomy attached to the content type

Hey guys,

I met a really strange problem here.

The situation is that i have one staging server(SS) and my local pc(PC) running the same project. When i exported the database from SS, and then create one new database in PC, import the database exported just now. Go to the backend of PC, i found that all the taxonomies assigned to content types lost. That means on the staging server when you create node, you will see box for you to select the taxonomies assigned to this content type. But in PC all the taxonomies assigned to the content type were lost which means you can't select taxonomy anymore when you create node. Even i add a new vocabulary and then assign it to the content type(eg: page) and then go to the page creation page, i can't see the new created vocabulary to select.

That's the detail things. If anything not clear, plz let me know.

Any suggestion or advice appreciated. Thanks
