When I try and edit any of my theme files by entering comments //,# or /* ... */ they just show up as text on my website. I'm guessing there is a pretty easy fix to this but I'm brand new to WordPress and I can't seem to figure it out.
I'm using 2.9.2 (tried the 3.0beta and had the same problem). I've tried using different themes, including the default, and have no plug-ins active.
What am I doing wrong? I realize I could upload file changes via FTP, but I thought that was one of the points of the Theme Editor- being able to change your code via browser.
