This block took much longer to locate than I was expecting. phpList is a HUGE program and finding where things are originating from isn’t as straightforward as I’d like. The lesson this time around (again!), was to look at the HTML of the rendered unsubscribe page and the div that surrounded the block. Then I searched for the string
clear: both; font-family: arial, verdana, sans-serif; font-size: 8px; in the phpList folder to see where it showed up – connect.php.
