Update page not loading

Hi Ray, I have recently upgraded a site to PHP7 and I have one DA update page which is no longer loading. I added error reporting but it's not showing any errors - I just get Chrome's "This page isn't working" error. Could you possibly take a look for me? Copy of the page is attached.

It looks like some of the recordset references weren't updated from MySQL to MySQLi. Do a find and replace to replace:

$row_WADAtargetarticles['Provider']

with:

$WADAtarget_articles->getColumnVal('Provider')

I've done that but it's still not loading, although I am at least getting an error message now:

Warning: mysqli_stmt::bind_param(): Undefined fieldtype - (parameter 2) in /var/www/vhosts/mydomain.co.uk/httpdocs/webassist/mysqli/rsobj.php on line 208

Fatal error: Uncaught Error: Call to a member function fetch_fields() on bool in /var/www/vhosts/mydomain.co.uk/httpdocs/webassist/mysqli/rsobj.php:211 Stack trace: #0 /var/www/vhosts/mydomain.co.uk/httpdocs/management/target-articles_update.php(24): WA_MySQLi_RS->execute() #1 {main} thrown in /var/www/vhosts/mydomain.co.uk/httpdocs/webassist/mysqli/rsobj.php on line 211

This was actually a page you helped with last month when it wasn't loading and you managed to fix it. I've obviously un-fixed it! Any chance you could take a look for me? FTP details in PM.

Line 23 you have:
$WADAtarget_articles->bindParam("-", "".($_GET['ID']) ."", "-1");

it should be:
$WADAtarget_articles->bindParam("i", "".($_GET['ID']) ."", "-1");

Thanks Ray, that fixed it!
