Whenever I edit any theme code in my Dashboard -> Appearance -> Editor and try to save it, the file is not saved and it automatically redirects me to the homepage.
I don't know why is this happening. I cleared the cache through the W3-Total Cache plugin.
A few hours before I did the same process, it was working perfectly.
But now, I can't tell what the problem is.
I also tried the same process in a different browser: the result is the same.
I'm using the latest version of WordPress (Version 3.0.4).
