smartweb,
Thank you! I think you have solved the issue. I suspect the last image I uploaded (and then immediately updated the theme) might well have caused this issue as it is narrow and tall. I can see how it might “blow” one page, but I’m surprised it has caused this problem with all of them. I’ll take it out, resave the page, and see what that does.
Thank you for your input! Much appreciated.
Brian
