Hey agrant31,
You’ll want to double check your wp-config.php file to make sure that the DB_* settings reflect your database name, database user and database password are correct. You’ll also want to make sure that your database table prefix in that file matches what’s actually in the database.
Without being able to look at the wp-config.php file and database it will be difficult to know the exact cause of the issue but these are the most likely reasons. Your hosting provider should be able to help if you need more hands on assistance.
