Q: On OSX Yosemite, when I open any page in Safari, there is a question mark inside of a blue box where there should be a displayed image. This just started today. What should I do?

1. From the Safari menu bar, select

          Safari ▹ Preferences... ▹ Extensions

Turn all extensions OFF and test. If the problem is resolved, turn extensions back ON and then disable them one or a few at a time until you find the culprit.

2. Select

          Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data...

and confirm. Test.

I have the same problem, but only on FB. And this did not resolve my problem. Still trying to find a good solution.

You might want to consider starting a new discussion. Since this one is marked solved, less people are likely to look at it. You can link to this one.

Did you find a solution to the problem? I am still looking for one.
