Deprecated Code
 

After much struggle trying to get sourcebans++ to properly install on my website, I finally managed to install composer and get the website up and running. The only issue is, I see the error:

"Deprecated: Creation of dynamic property ADORecordSet_mysqli::$adodbFetchMode is deprecated in C:\MyDirectory\XAMMP\htdocs\sourcebans\includ es\vendor\adodb\adodb-php\drivers\adodb-mysqli.inc.php on line 1513"

on my banlist, commslist and index.php?p=admin&c=admins. I was curious if there was anyway to remove this error or what this error might be caused by?
