Safari & Chrome Issues

I have googled, spent 3 hours on the phone with Apple support and nothing.

I have the Valenti theme and some of the links are broken. For example:

1. I can’t upload a logo. Simple right? I click on the + bar to upload and nothing happens. I have tried it on 7 of our Macs and nothing. Tried it on a friend’s pc and it worked just fine.

2. I also can’t click on other random things that I know are links, it simply won’t open them. I don’t think it’s a theme problem because I had similar issues with a previous theme.

3. With my old theme, when I would make changes to my theme, I couldn’t see the changes. I would get frustrated, go to bed and get up the next day and low and behold the changes were there! I usually would have to clean out my cache and SOMETIMES that would work but not all the time.

I never had any problems until Iphone 6 came out. But then, why is it not working in Chrome either? It makes absolute no sense. I have spent 3 weeks and countless #’s of hours and no one seems to know why?

I’m at my wits end. Nothing should be this difficult. Is this a WordPress Bug? Or ??? I have the lastest updates of Javascript & Safari & Chrome. I even downloaded Yosemite thinking that may be the problem. So far, not the case.

Thanks for any insight.
