Problem loading photos with Safari

I’ve been doing a simple adding of photos with WordPress to our website for more than a year now. About half a year ago, I had a problem where I’d get an error message saying, “Safari can’t open the page because it could not load any data from this location.” I wasn’t doing anything different (like now), and Support asked if there was some cookie blocking or security that was “on” that wasn’t on before, but that wasn’t the case (like now.) I noticed at the time that others on the support board had the same question/problem. About a week passed and suddenly it worked again. Last week I got the same error message, but found that if I attempted to “Add Custom Field”, oh, about 10 times, it would work. Needless to say this is very frustrating. I’m really afraid some day this will cease to work altogether with Safari. Are there upgrades currently or recently happening that might have caused this?

Many thanks,
Lena
