[fw-mvc] autoloader problem

Hi ZF community,

today i take a look at apache error_log and I got this error message :

[Fri Nov 27 16:44:33 2009] [error] [client 114.48.30.190]
PHP Fatal error: Uncaught exception 'Zend_Loader_PluginLoader_Exception' with message 'Plugin by name 'Cdn' was not found in the registry; used paths:\n
Zend_View_Helper_: Zend/View/Helper/:/www/website/application/views/helpers/' in /www/website/library/Zend/Loader/PluginLoader.php:406\n
Stack trace:\n

Then I try to put Cdn.php under www/website/application/views/helpers/ .. the above error gone .. and i got this error :

[Fri Nov 27 16:47:50 2009] [error] [client 114.48.30.190]

This error does not happen to any client .. but one in particular was [client 114.48.30.190] .. keep receiving this error .. any idea how to fix this?

Thank you very much,
Ari
