Safari cache will not clear......cannot get to current version of website.

I design our company website. It was recently moved from Hostgator to Flywheel and I am unable to open a current version of the site or make changes via the admin page on Word Press and have it go live. I have tried to clear the cache, but it will not clear. Also, this is happening on my iPad 2 and my husbands MacBook Pro. I cannot un-install safari because Maverick's won't let me. I AM able to make changes and see the current live version on the Dell PC laptop I have. Any ideas???
