WordPress newbie here, so I'm sure I'm missing something. I just copied the code from <http://wordpress.org/support/topic/11211?replies=21#post-67536>, pasted it into a new PHP document, and uploaded it to my wp-content/plugins folder. So far, so good.
Except that when I view the plugin in my Plugin Management list, instead of neat cells of plugin name, version, and description, I see large chunks of the actual plugin script itself. I'm afraid to activate the plug-in, lest I screw something up.
I've compared the syntax and formatting of the script to the hello.php that came with the WordPress install, and can't see any differences that look like they'd "break" anything, but ignorance rules the day over here.
Any ideas what I might be doing wrong?
Thanks in advance!
