I’ve just discovered what I THINK may be causing this problem.
Using the Inspector (right click - inspect), I’ve found what might be additional elements AFTER the footer.
This area shows up when I hover on “*, *: before, *:after” within the inspector.
I hope the attached screenshot explains what I mean.
Am I right in assuming that these are additional elements?, and if so, how can I get rid of them so that there is nothing after the footer?
Thanks in advance for any and all help on this.
