Broken by PHP 7

[oldspice]

I have two Coppermine sites both with version 1.5.4?
Myhosting company has just updated to PHP 7.0.19 and it immediately broke my Coppermine Galleries.
How can I update my installations to start working again.
The error messages include "Fatal error: Uncaught Error: Call to undefined function mysql_connect() "  "183 Stack trace: #0 "
As I can't get to the 'Front End', I wonder if I am able to do an update using FTP ?

You will need to get your hoster to help you run PHP 5.x again.
Then update your Coppermine sites to the current 1.5.x version.

Followed by upgrading them to version 1.6.x.

Then you can return to using PHP 7.
