Internet or Firewall is blocking some content from youtube.
I been experiencing problems with my Youtube for some while now, every time I go into Youtube all the thumbnails wont display, it just appears as a red x in a top left hand corner, also when I click on someone profile their background image wont appear, it just stays blank.It just happens on youtube no where else, sometimes like 1 out of 30 times some of the thumbnails do appear but not all of them, and it takes a while. The videos work fine.
I tried a lot of things like;
Download different brewers ( safari,opera) the same thing happens there.
Clearing the catch
Making sure that "display images" are clicked in on Internet options
I reseted my internet options to the original setting
nothing seems to work, :(
