Error while trying to install Drupal modules
If you are trying to install a Drupal module, and get a message similar to the following one:
The specified file temporary://filename could not be copied,
because the destination directory is not properly configured.
This may be caused by a problem with file or directory permissions.
More information is available in the system log.
you can solve it by going to Configuration > Media > File System and changing the value of the Temporary directory field from /tmp to tmp.
This error happens because of the wrong setting of the temporary folder when you first install Drupal. When you change this setting you will be able to install your desired Drupal module.
