Do you have those errors without my plugin as well? Because they all seem to be caused in changedata.php before my plugin runs. You can try the following:

Find line 115 in changedata.php, it should be this:

Code:

if ( file_exists($file) && ($url != $_POST['existing-url']) )

Now change it to this:

Code:

if ( file_exists($file) && isset($_POST['existing-url']) && ($url != $_POST['existing-url']) )

Tell me whether that fixes your problems, if it does I will add that change to the core.

(It’s hard debugging a problem when you don’t see it yourself.)
