function mysql_connect()

Hello

I’ve recently started having problems loading store locator and I found the following in the store locator error log:-

[06-Jun-2018 13:25:19 UTC] PHP Fatal error: Uncaught Error: Call to undefined function mysql_connect() in /home/<my-site>/public_html/wp-content/plugins/store-locator/sl-xml.php:14
Stack trace:
#0 {main}
thrown in /home/<my-site>/public_html/wp-content/plugins/store-locator/sl-xml.php on line 14

I’m running on php7.1

Any ideas?
Thanks
Chris
