Error querying database when migrating localhost to server

So, I created a form that allows you to add a place, category and image to my database. All this works fine on my local host and correctly inserts data into my database. However, when I post the form on my website, I just get a "error request database". message.

I modified the connection files so that they have the correct information about my server, database name, username and password.

I connect to my database in two different ways. One of them uses mysqli:

<?php
$dbc = mysqli_connect("localhost","root","","ssdb") or die (mysqli_connect_error() );
mysqli_set_charset($dbc, 'utf8'); 
?>

And also with mysql:

<?php
$con=mysql_connect("localhost","root","");
mysql_select_db("ssdb",$con);
?>

In my form, I connect to my database to get the categories you can select using the mysqli function so that it can work?

, mysql php 7+, php 5.6..something.
