after a fresh install on an ubuntu 16.04 with php7.0, everything works fine excepted the "import" part of the admin board.
after activating the debug in config.php, i get this message:

mysql_connect is a deprecated function, how to workaround this ?

Swennet

PHP7 no longer uses the mysql_connect function. Instead, it has been replaced with mysqli_connect.

A simple solution would be to do a search and replace. Search for "mysql_connect" and replace with "mysqli_connect" in your /vanilla/applications/dashboard/models/class.importmodel.php file.
