Topic: Database reported: Duplicate entry '0' for key 2 !

A few minutes ago I could post new threads

Now I see this error when creating (I turn on "DEBUG mode" in config.php)

An error was encountered

The error occurred on line 1901 in /public_html/forum/include/functions.php

Database reported: Duplicate entry '0' for key 2 (Errno: 1062).
