I'm trying now to replace my 468x40 post banner (adsense) with an Amazon 468x60 banner.
I followed the instructions on this tutorial:

and everything was perfect until I tried to "Save Changes" in the Widgets.
When I click on "Save Changes" I'm forwarded to a 404 page - if I go back and try to save changes without Amazon's html code, everything is fein.
I also tried today to update my index.php file and I was also forwarded to a 404 page (eventually I modified it with the Winscp)
Any idea what might cause it?
