24px margin at bottom of custom footer

I thought I was losing the plot, however, every site I have built with Divi (about 10) have now got a 24px margin at the bottom of the custom footer. Did Divi manage to install a bug with their latest release? If so, any chance of fixing this bug so I don't have this problem anymore? Thanks.

Examples;

No, weirdly it comes a goes. I've seen it acting correctly, but for an example, this is happening now. Checked on Chrome and Firefox, so not a browser issue.

This only started happening recently, it used to be fine, but it has moved all my sites off the bottom and created this whitespace, with two exceptions;

I've tried just about everything, javascript, HTML and CSS, but I'm getting nothing. This is happening in the body tag, not the footer, but I can't find why it would happen. It isn't the reCaptcha terms as I have removed the div and I still get the whitespace. This is why I can only think there is a Divi bug in the latest release, it would make sense if all my sites just suddenly have this appearing?

It's getting frustrating now.

 

Hi and thanks for replying, yes I've tried them logged out, I can't think of any way I haven't tried. It's very frustrating that I see this margin but you don't. I know when I do see this it is coming from the body when I hover over in Chrome devtools. But there is nothing in the body tag to suggest there is a problem. I'm not sure what to suggest to further this.

 

What about https://acepower.com.au? Again, tried this in Chrome, Firefox and Edge and getting the same margin plus the ETModules font family doesn't work, does this show for you?

 

Once again, thanks for your help. I do have Really Simple SSL on some of the websites, but I chose https://gscplumbing.co.uk at random that did not have RS-SSL and added it. It hasn't made a difference sadly. I also went to another site I've done, my oldest Divi one, in fact, https://carole-annsclassroom.co.uk, I did have RS-SSL on this one but I still get the margin. I've tried the padding changes and also, on advice from some RS-SSL notes, minified CSS and js (separately) and Options -> Builder -> Advanced disabled Static CSS File Generation. No joy. I'm going to test on another laptop and see what happens. If I don't see this margin I can only think my settings in Windows10 have changed (involuntary), although I would expect this to happen on all websites and not just mine.

I've also noticed this margin is happening on;

Whatever the outcome I'll report back here.
