error message This page is not working when I add a database connection

I am using Dreamweaver 2021 I can see my static pages on the web but when I add a dynamic page (my connection to the database) I get the following error HTTP 500; This page isn’t working www.testkaren.site is currently unable to handle this request.
HTTP ERROR 500

Try adding this to the top of that page:

<?php
ini_set("display_errors",1);
?>

That may give you a better error message.

Okay i did put the code in at the top of the page and here is the message: Fatal error: Uncaught Error: Call to undefined function connect() in /home3/q300119/testkaren.site/index.php:4 Stack trace: #0 {main} thrown in /home3/q300119/testkaren.site/index.php on line 4

Below is line 4
<?php virtual('/Connections/MyConnection.php'); ?>

and attached is my MyConnection.php (when I upload this I get no error message)

ps: I am rewriting all of my websites (dreamweaver cs3) because my pc crashed and I can no longer get cs3)

Please attach a copy of the index.php file referenced in the error.

I have attached the index.php file

The error doesn't seem to match the file. Can I get FTP access and a URL to reproduce so I can debug the file live?

Can I get FTP information? I want to try debugging the live page to figure out what is going on.

is this what you need for the ftp info? (see attached)

I also need the password, which isn't visible in the screenshot.
