my header disappeared

I also just upgraded to wordpress 3.5, I don’t know if maybe it was this…

Your site seems to work quite fine. Clear caches and try again to see if the problem persists.

I’m looking at it also from other computer, but the banner image I had as a header and also the ad I had before the posts are not there anymore.
The ad is fine anyway because I have the code, but I don’t know if I can do the image…

You may look at your theme settings and re-upload the image. It is currently not there and it seems it might have gone while updating your theme.

Thanks. Done.

You are welcome!
