How to Refresh / Flush WordPress Permalinks

Whenever a new custom post is added through a plugin or code, WordPress permalinks usually need to be flushed. Also, that's required after transferring the site to another domain.

• Step 1: In the WordPress admin area, go to “Settings > Permalinks”
• Step 2: Click “Save Changes”
• Step 3: Permalinks and rewrite rules are flushed.
