After Migration From dev, Only my Links to the Homepage Still Redirect to dev

You most likely have invalid URLs in the database, however, it’s also entirely possible to have a hard-coded URL in somewhere in the theme or perhaps a plugin, or even .htaccess.

You could always search your entire database for the URL, and make adjustments manually. However, please note that if you make any adjustments to a URL within serialization, you should de-serialize it, make your adjustment, then re-serialize it again, before making the update in the database.

If you want a more automated approach to search and replace all occurrences of a string (A/K/A – replacing URLs), you should take a look at WP CLI.

• WP-CLI Commands :: wp search-replace

To further troubleshoot…

• Disable all plugins.
• Make sure all drop-ins are removed for testing purposes.
• Verify there’s no cache subdirectory in the directory
  ./wp-content/.
• Verify contents of
  .htaccess in the root
  directory of WordPress.
• Verify contents of wp-config.php file in the root directory of
  WordPress.
• Clear browser temporary files and caches or just try another browser.
