WordPress moved directory

Hi. I don’t know if anyobe can help me but I originally made my site on a different directory off the main ( i.e – domain domain.com/test)and moved the whole site over to domain.com when the site was relaunched now I have a problem because the posts and widgets seem to run from the old index file from the /test directory I originally set the site up on. How do I get wordpress to only run from the main domain?
