Cant't get it to work

What am I doing wrong?

I have made a copy of working code from server with php5, and moved it to server with php7.

I get:

[Thu Sep 28 22:09:17.456336 2017] [:error] [pid 32433] [client IP:38958] PHP Warning: mysqli_query() expects parameter 1 to be mysqli, null given in /var/www/html/FUmedlem/mydql2i/mysql2i.class.php on line 426, referer: http://IP/FUmedlem/index_auth.php

Looks like you are not connecting to the database.

1) Make sure your credentials are correct for the mysql database on the new server (if using localhost) or that you are properly connecting to the mysql server remotely.

2) If the problem persists, after your script connects (probably somewhere in script init, config or connect file) check the value of mysql2i::$currObj to see if it is a mysqli object, you can use something like...

echo '<pre>';
var_dump(mysql2i::$currObj);
echo '</pre>';
die;

If it is null, you need to track down the connection issue. If it is a mysqli object, then the package is not properly handling the connection and I will have to run some tests on my code.
