Wordpress uses permalinks to connect URL’s to individual pages and posts. These can stop working when a update is made, installing plugins, and migrating the website. When this happens the home page will load but the the links or tabs to other pages on the website will return a error. Resetting the permalinks will fix the problem.
Log in to your Wordpress admin dashboard. You can use YourDomain.com/wp-admin or YourDomain.com/wp-login.php to reach the login.
Select the Settings tab in the left navigation menu. Choose Permalinks
Record the current permalink setting being used. If using a Custom Structure, write down the setting. We will be changing the setting and then changing it back. The Permalink settings are Plain, Day and name, Month and name, Numeric, Post name, and Custom Structure.
Change the setting to something different that the current setting or what you want to use.
Click the blue Save Changes button
Select your original setting and click the blue Save Changes button
You have now reset the Wordpress permalinks. Check your website to make sure the pages and posts are working.
Permalinks are an important part of your WordPress SEO and have many options to choose from. We suggest using the Post Name in your Permalinks settings.
