Joomla upload package Warning! Failed to move file.

So you have just found the latest and greatest joomla plugin/component that will solve all of life’s terrible problems only to get a wonderful error: Warning! Failed to move file.

The good news? This error is very easy to fix as it is basically telling you that Joomla doesn’t have the correct permissions to upload the file and install it.

1. Set the permissions of the tmp directory which is located in your joomla installation directory
2. The module/plugin/component may be made for an earlier version of Joomla, if this is the case you will most likely be alerted to this fact and you can go ahead and turn on the System Legacy Plugin which is available in the plugin manager.
