Strange problem with updates (Wp Admin)

[Igal]

Hello everyone,

I'm trying now to replace my 468x40 post banner (adsense) with an Amazon 468x60 banner.
I followed the instructions on this tutorial:
http://studiopress.com/support/viewtopi ... =18&t=4378 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?

Thank you

Show us the Amazon html code.


HTH,

There's definitely no problem with the code. It works perfect with a Notepad (.html)
I have the same problem if I try to upload Adsense to this spot, I've got some kind of a problem - probably I modified one of the codes and now I don't know which.

The strangest thing is that I was sure that If I'll download a new version of the wordpress and will rewrite all the codes, the problem will be fixed, but it wasn't.
I was actually hoping that someone here had a similar problem so he/she'll be able to give me a hint or where to start looking for the problem.

I'm adding 4 screenshots that maybe will help you understand my problem.

Thanks again.

And here is the final Screenshot, after I click on Save changes (with the code inside)

Thank you!
