 * Hello! I recently upgraded my server to php5 and have found a plugin that quit
   working. I’m personally not incredible with php so I don’t know what could be
   causing this issue. Maybe someone here can look over this and see if there is
   anything huge that would be causing it to not like php5?
 * Thanks!!!
