Hello, Yesterday, I updated my installation of revive-adserver, from version 4.1.4 to version 4.2.0, after uploading the new files no update screen appeared, and I have not seen any error message or problem in the application, the only detail is the message in the update section (www/admin/updates-product.php):
He is currently using Revive Adserver v4.2.0 (warning: database is stamped as v4.1.4) running under Apache, PHP 7.1.14 and MySQL 5.6.41-84.1.
Sorry my english is bad.
Saludos :-) ...
