Cannot instantiate non-existent class: messagestack

[mylle]

I get this message when going to admin/index.php

 

Fatal error: Cannot instantiate non-existent class: messagestack in /home/feelfree/mirbycom/catalog/admin/includes/application_top.php on line 148

 

Anyone know why?

 

Thanks for the help! :D
