Fatal error: Call to a member function

[jennki]

I found a problem in my website setting up with oscommerce that after I changed my password for my account login.

 

In the "My Account Information" Page, I change my password in the "Change my account password" page. I typed in my existing one and typed twice of my new password and then "Continue", error comes up in a blank page showing :

 

Fatal error: Call to a member function on a non-object in /home/.argus/eming/ecfilm.com/catalog/includes/functions/html_output.php on line 78

 

 

What should I do to make it works? Please advise. Thanks.
