Converted cleanly from 3.0.0 to 3.0.6 by replacing all files and running database_update.

When clicking on Jabber Settings in ACP, I get error:

[phpBB Debug] PHP Notice: in file /includes/acp/acp_jabber.php on line 53: Undefined index: jab_use_ssl

When clicking "submit" I get SQL error: Column 'config_value' cannot be null [1048]

SQL

INSERT INTO CN_config (config_name, config_value, is_dynamic) VALUES ('jab_use_ssl', NULL, 0)
