Hi, I have been searching for a solution for this issue for quite a while but I only saw similar problems in older posts from users running Mountain Lion. As you can see from the image I attach the top bar doesn't show correctly with YouTube image and icons to appear blank. I have 2 macbook pros same model same configurations running both the latest versions of El Capitan and Safari. One of them shows YouTube page correctly but the other doesn't. What I have tried so far: - Empty Safari Cache (both from Develop menu and from Safari>Clear History) - Disable all extensions (only running adblockPlus) What else could I try and do to resolve this? Thanks in advance.
