Use the extension from here: http://www.sitesplat.com/phpBB3/viewtopic.php?f=17&t=3200 for phpBB 3.1.x (Min v. 3.1.10) and higher, included the recently released phpBB 3.2.0
How to Install a phpBB extension:
Download and unzip the current release. Copy the unzipped folder to the ext directory in the root of your forum. Note, if a phpbb directory already exists in your ext directory, do not overwrite it; just copy the extension-name folder to ext/vendor/extension. Navigate in the ACP to Customise -> Manage extensions. Look for extension-name under the Disabled Extensions list, and click its Enable link.
