 * Hi,
 * I am using a plugin which has updated recently for the flickr api authentication
   change. However the plugin class seems to be loaded into memory and it doesn’t
   look like you can undeclare a class!
 * The class is declared with:
 *     ```
       if ( !class_exists('myClass') ) {
   
         class myClass {
         }
   
       }
       ```
   
 * The plugin update has changed this class (new links stored in variables), but
   because it has already been declared the new class code never gets read. I proved
   this with echo statements, and I can see that the object instantiated has the
   old class variables set.
 * I am using wordpress which is hosted by my provider. I do not have the ability
   to restart my server. My wordpress is at the latest version. I have tried disabling
   the plugin and reactivating it. I have also tried deleting it completely and 
   reinstalling (via FTP and via the worpress page). Nothing has worked. I even 
   tried changing my php version on my web server! This class is declared and does
   not want to let go 🙁
 * I have hacked my way around it by renaming the class and updating any reference
   to the new name, this loading the new class code. This seems unnecessary and 
   I am sure there must be a way around this.
 * Does anyone know how I can unload this class and reload the new one?
 * Thanks,
    Stewart
