Problems updating user information

Hey guys,

Wondering if someone could help me. I'm running into an error when trying to update user information for any of my members (myself including). User creation goes smoothly but as soon as I go to the "Update Profile" page, change something and click "Update Profile" button I get a horrible error claiming:

Error (InvalidControllerActionError)

Invalid controller action account::card()
Error params:
File: .../projectpier/environment/classes/controller/Controller.class.php
Line: 72
Controller: account
Action: card
Backtrace:
#0 .../projectpier/environment/classes/controller/PageController.class.php(62): Controller->execute('card')
#1 .../projectpier/environment/classes/Env.class.php(119): PageController->execute('card')
#2 .../projectpier/init.php(138): Env::executeAction('account', 'card')
#3 .../projectpier/index.php(9): require ...
#4 {main}

Does anyone have any idea why projectPier fails to find the action that is supposed to update the account?

Thanks!
