Failed to install Admin tools

[erioho]

I installed Piwigo on Ubuntu Server 18.04, with Apache and PHP7.2. It said there is an update for admin tools but failed to install. A pop up said "Error" but no further description.

Deprecated: Function create_function() is deprecated in /var/www/html/plugins/AdminTools/include/MultiView.class.php on line 41

This message show at the top of the page when I activated admin tools. Is there any ways to update it manually? Or wait for your solution? Thanks.
