There's nothing about changing a domain name / hostname to imply that you need to move anything at all. Those are simply DNS changes. You would only need to change $CFG->wwwroot in your Moodle config.php to reflect the new URL.

You may also need to run the replace script to fix up any internal links in the database.

This is very, very bad but hopefully points you the right way. I'm just adding some space at the top with a couple of margin classes.


 
<div class="mt-5">&nbsp;</div>
<div class="mt-5 alert alert-danger"> 
  <b> Text here </b> 
</div>

You said, "the following errors" but did not show the errors.

The errors from the code checker just seem to be mostly style issues. Except the last one - you would normally need a require_login().  The others should be fixed but wouldn't stop it working.

....moving to General developer forum.

I don't use them, but I think that the idea of these scripts is that they create the user accounts *before* the user logs in.
