I've never had a problem with editing my theme files before, but now that I've upgraded WordPress to 2.8, I'm having a weird issue. When I try to edit a theme file such as "header.php" and hit "update file", the browser redirects me to my blog's homepage and doesn't save the changes to the file.
I checked to see if the files were chmoded differently, but they're not - all are writeable, so I am not sure what the problem could be.
Is anyone else having this issue? It's extremely annoying to have to log in to FTP to edit a theme file... any help would be MUCH appreciated!
