 * So I have tried to follow tutorials, but I don’t understand. I installed the 
   plugin, I activated, but I just get this error:
 * Fatal error: Call to undefined function: wp_theme_switcher() in /home/breath/
   public_html/test.php on line 1
 * I don’t understand why I’m getting this error and I don’t know how to fix it.
   Can someone help me?

 * “Call to undefined function: wp_theme_switcher()” denotes that “wp_theme_switcher()”
   has no definition. This would only be the case if the plugin were inactive. Please
   make sure that the plugin is active and that you have the latest version.

 * What else is in test.php? Is it WordPress aware? (I suspect not, since the error
   occurs on line 1.)

 * Good catch, Kaf. Even if it is WordPress aware (IOW, it’s part of WordPress),
   try putting it inside your sidebar.php instead.

 * Yes it is the lastest version, and it is activated in the plugins panel, so I
   don’t understand why its not working.

 * Theres nothing..I did what you said and put it in the sidebar file, and it worked.
   Now I don’t understand why it has to be in that file, for it to work.

 * Go to the index.php file in your WordPress directory.

 * I couldn’t get this plug working either. I kept getting a header error, it made
   ONE semisuccessful themeswitch (still “header” errors, but it showed the right
   theme) then it wouldn’t work again. I can’t tell you what the header error is
   exactly, since I had to deactivate the plug (I use the site as part of my portfolio
   and just bid a couple jobs- can’t have errors showing now!) I can tell you that
   the plug was trying to produce header stuff that was already being produced by
   either my theme or by WP itself, if that makes sense.
