I don't know if it is just me but all my adsense adverts have disappeared. Last night I had a error message in the place of adverts, today just an empty space. Has it happened to anyone else?
No, not to me and not on any site i visited in the last 24hours that uses Adsense either. Did you make any recent changes to you site's code lately? I suggest you contact Adsense google.com/adsense/support/bin/request.py
Look at the code in your site. Is it OK? Go back to your Adsense account and paste back, then see the results? When you were selecting the ad format, did you choose white space if there are no ads? Else, you may have been banned, contact support.
Maybe I am banned. I've selected show public adds so something should show up. Few minutes ago I checked my web site from my friends computer and first it said that my site was off line and at the second attempt it appeared with all the adds in it's place. Now I am at home and there are no adds again. I went on to googles adsense/case study page google.com/adsense/success?sourceid=asos&subid=ww-ww-et-resource_box&medium=link and I can't spot any google adds on the web sites that are featured which makes me think that the problem is wide spread. In the meantime I did contact google and I am waiting for their reply.
It might be geo-based. I'm in Asia and I've noticed the adsense ads disappear on some of my favorite article sites. Hopefully, (for the publishers' sake) it's temporary.
