There are a couple of things you’ll need to check.
If you have changed your domain name:
Log into PHPmyadmin
Locate your WordPress database
Search in all tables for the old domain name
Update any occurrences of the old domain name to the new one
If you have moved servers:
Open up your wp-config.php file and make sure all of the settings are up to date. For example, if you have changed your hosting you most likely would have had to update this file to change the database that you are pointing to.
