I just upgraded to el Capitan which might be the reason. If you go to the very bottom of the page you will see the bottom logos have a slight ghosted image just below them. All I did is “move” the graphic on the page and a ghosted image stayed in place. Never have seen this before. It can be seen across platforms and browsers.
I really don’t know what to say about this. Or, maybe, how to say anything about this.
What I can say, having looked at the html output, is that you have-- in several places-- duplicate content. It’s not limited to the one graphic… it is also text and other images and text.
I can’t speak to OS X Captain & Tennille, but it looks to me like perhaps you have copy-dragged some items or otherwise duplicated them in place. This is the only explanation that makes sense-- short of you suffering from multiple designer personality disorder or having a secret evil twin.
What makes it so hard to diagnose is that page is so very full of stuff… you may want to work on a copy so you can eliminate things which may be covering up other things which is what the problem seems to be (I say it like that because I started removing things and that is when I found other things behind them).
Anyway, that’s about all I think I can say about this, so…
Not saying this is it - but sometimes one can find duplications from the Master Page and individual pages. Deleting the doubled items from the individual page and using “reapply master” will resolve this.
