Troubleshooting “Error establishing a Redis connection” during WordPress migration

An issue like this is almost always related to cache plugins going haywire after a site is being migrated.

  1. Delete the folder of the plugin that’s using Redis via your hosting’s file manager or FTP/SFTP.
  2. Check if the error goes away by visiting the pages of your site where you usually see the error.
  3. If it does, reinstall and configure the deleted plugins in the new installation.
