 * Hello,
 * I have written a class and saved it in its own file inside my theme folder (using
   the BlankSlate theme). I want to include the class in such a way that it is available
   in every single file for the theme (such as “sidebar.php”, “header.php”, etc),
   but using “require_once()” inside the “index.php” file does not work.
 * How do I do this?
 * Currently I have used the “require_once()” function in “header.php”, but when
   I want to reference a member function inside the “sidebar.php” file I get an 
   error telling me I’m calling a member function of a non-object. In other words
   the class is not available inside the “sidebar.php” file.
 * How can I achieve this?
 * George

 * Put the `require_once()` on your theme’s functions.php file, not on template 
   files.
