# Plugin update issues or errors

### List of errors

There are a few possible error messages the WordPress updater can throw:

* An error occurred while updating Ajax Search Pro: Update package not available.

### 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](/plugin-updates/manual-updates.md).
* You may have a proxy server or a firewall active, make sure to whitelist the plugin update server: **update.wp-dreams.com**
* 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.

The best alternative is to [update manually](/plugin-updates/manual-updates.md).
