[Mediawiki-l] error when blocking users

[Achim Stumpf]

Hi list,

When i try to block a user, i get an error:


  Database error

A database query syntax error has occurred. This may indicate a bug in 
the software. The last attempted database query was:

    (SQL query hidden)

from within function "Block::insert". MySQL returned error "1054: 
Unknown column 'ipb_enable_autoblock' in 'field list' (isintra1.fra)".

I am using:
Mediawiki 1.9.0
PHP 5.2.0
MySQL 5.0.27

Thanks,

Achim
