Error when I go to live server

I have moved to files to my live server to give a quick test.
On my local server I can login to the dashboard and click through to edit my profile, all works fine on local.

Moved to live server I can login and view dashboard ok but then when I click through to edit profile it throws this error

Fatal error: Uncaught Error: Call to a member function close() on null in /home/sites/5a/7/7a4a121f55/public_html/webassist/mysqli/rsobj.php:229 Stack trace: #0 /home/sites/5a/7/7a4a121f55/public_html/profile.php(7): WA_MySQLi_RS->execute() #1 {main} thrown in /home/sites/5a/7/7a4a121f55/public_html/webassist/mysqli/rsobj.php on line 229

profile.php and rsobj.php attached

I am using Beta version of DataBridge

Live server is running PHP 7.1

Thanks

Can I get FTP access to the server and a URL for debugging? It looks like an error in the code, but I'd like to do some testing to see why it occurs.

As requested

I can see the error on the site, but the FTP information doesn't seem to work for me. Please verify there are not any typos and that there aren't IP Address restrictions that would prevent me from getting through.

Apologies I have unlocked the ftp from IP restrictions and I have tested the login details

Thanks

You had the wrong database server in your connection file. I updated it to match the other connection you had defined and the page loads properly now. I'll update the file to provide a better debug message in the next release.
