On wifi WordPress site is showing non-updated site?

I have been having this issue for over a week and no one can solve it so far. I thought it was specific to just my iphone but now I know it is not.

I have been updating my wordpress site https://24days2skinny.com almost always on my desktop at home. I realized last week that on my iphone my site was showing an older non updated site. March archive missing, widgets wrong, etc… when I turned off wifi on my phone my correct site showed up. this was happening on other phones in the house and tablets.

Talk to ISP-nothing they said was wrong on their end.

Bought a new laptop yesterday for vacation got to my destination. Turned on laptop went to website and again OLD non-updated site showed up on NEW laptop! Thought it may be Chrome (because of saved settings)

tried IE and at first my correct side showed then 2 min later I was asked to re login to my WordPress site (it signed me out) I logged in and Old site showed up on IE.

It’s like I have 2 separate sites that don’t sync!

The really crazy part is that I will get legitimate comments on the old site that don’t show up on new site and vice versa..

I’m on Window 8. I’m using Thesis 2.1 theme. Not sure what else you need.
My updated site has March Archive on it which is in sidebar toward bottom has just one post. That’s the best way to check which version of my site your seeing. any suggestions???
