 * Hi there, I’ve included classes.php in my core plugin file.
    In classes.php I
   try to autoload all my classes. When I activate the plugin it should autoload
   them, but instead I’m getting an error that it tries to autoload a theme .class.
   php, which isn’t even in my classes folder.
 *     ```
       spl_autoload_register( function($classname) {
   
           $class      = str_replace( '\\', DIRECTORY_SEPARATOR, strtolower($classname) ); 
           $classpath  = plugin_dir_path(__FILE__) .  DIRECTORY_SEPARATOR . 'classes' . DIRECTORY_SEPARATOR . $class . '.php';
   
           if ( file_exists( $classpath) ) {
               include_once $classpath;
           }
   
       });
       ```

 * You should do some basic debugging. First, check what the value of $classpath
   actually is.
 * `echo $classpath;`
 * It sounds like that’s not correct so you should go back into your code to find
   out where it’s gone wrong.

 * Yeah my dumb fault, it was a long day and I was tired. I literally forgot a ‘.’
   in front of `'class.php'` to get classes like `location.class.php`
