 * Hi,
    I am seeing this error message when I install a new plugin to my site by
   UPLOADING IT.
 * Everything seems to be working fine and the error message doesn’t appear if I
   install a plugin via the dashboard without having to upload it.
 * The only thing I can thing off is that I changed media file sizes when first 
   setting up this WordPress install. Could this be related ?
 * Does anyone know what this means and how to fix it please ?
 * The error message:
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   wpthumb_delete_cache_for_file’ not found or invalid function name in /home/ehawebde/
   public_html/e-ha.co.uk/spc/wp-includes/plugin.php on line 235
 * Thanks in advance
