Resolving automatic update errors

There could be several reasons why the automatic update fails. Below is the list of possible reasons.
  • Server cache settings which cause the old package return from the server temporary folder. This can be very hard to debug, the best choice is to update manually.
  • You may have a proxy server or a firewall active, make sure to whitelist the plugin update server:
  • Trying to update on a multi-site network while you are just a node and doesn’t have the administrator permission.
  • The file/folder permission issue.
  • Plugin conflict. Try deactivating all the plugins and then try updating.
  • Missing Remote Get function or cURL package for PHP. In this case, contact your service provider.
