Today, When I was logging onto my Google adwords account. I got an “1×1 pixels” error. The page loaded normally in Firefox and Google Chrome except Safari.
Here is how you can fix this problem. This worked on Safari 4.0.4. on OS X Snow leopard Right click on the web page and you should see the menu like in the picture. Choose “Disable Safari AdBlocker” and then reload the page. This should fix the “1×1 pixels problem”.
