Web site won't load in Safari, on any device

I’m a new user of this forum, and not a programmer. But thought I’d see if this would get me anywhere. Since my update to WordPress 4.4, which happened automatically for my site, the site has not been able to load any pages made with posts in Safari. This holds true on all devices, Macs, iPads and iPhones. Other browsers work on all devices (I tried Firefox and Chrome). In Safari, simple pages, like my “About” page, will load OK. But the blog and portfolio pages will not load.

I did all the recommended things I know about — disable plug ins, etc — but no change. Does anyone know if this has happened to anyone else, and if so what can be done about it?

Thanks all!
