Contact menu item - Error in SQL Syntax

[parameter]

After I upgraded my Joomla site to 1.5.24 version, I have database error in my Contact menu item which worked fine before that. I didn't make any changes in contacts for long time.

This is the error that I get when I open Contacts in my main menu:

Code: Select all

I tried to create a new menu item, but this error remains. Any help?

It happens only when I set Contact category in menu link, but not with standard contact form.
