Hello, @donhetter,
I don’t know why it happens on your site because your site is working fine for us there is no issue as I already showed you in my previous response.
You said, “Is there a reason changing from lazy to default solved this problem?”
(Quite Possible because the Lazy loading in WordPress helps the web page load faster. It loads the images and other media elements only when the user reaches that section.)
You said “Would changing this setting to default have any other effects or negative effects on our website?”
No, this option will not make any negative effects on the site no need to worry about it.
Note: Once a thing is working fine for me and showing no issue/error how can I help you with it? You are facing the issue with other regions. It is possible that your server has set the restrictions for those regions. Did you ask your service provider about this issue?
If turning OFF the Lazy Load resolved your issue, then please keep it disabled.
Regards 8Themes Team.
