Remove Prefix for error exceptions

I am trying to access different areas of the site and trying access either members only, adding admin to url, trying to edit other peoples records and if I am logged in it adds the prefix to the error exception

 

Example:

Action ErrorsController::manage_error404() could not be found.

Action ErrorsController::admin_error404() could not be found.

Action ErrorsController::manage_error404() could not be found.

And so on….

How do you fix this? Did not see much info on this.

Any help would be appreciated.

Thanks 

Dave
