Problem Uploading the Back Up

hi, my wordpress is under the folder /site but i made a new one with different sql database under /fansite

i uploaded correctly, the sql from the old wordpress to the new one, everything seems to be uploaded fine BUT. all links forward to the old wordpress under /site/ and not /fansite/

how can i fix that?

as you understand i cant even login because it directs to the old admin panel

when i renamed the new wordpress folder /site/ i can see my messages, posts, ect but when i click on them i get errors

thanks
