Starting last night I noticed my ads had suddenly changed even though I didn't do anything. I have some 468x60's and the link color changed, although when I logged into my Adsense account it's still what it should be, it just shows up weird on the site itself. I also have a vertical banner that's set to all image ads and now it shows only text, but in the Manage Ads panel it's still set to images only. WTF is going on?
