Problems with postfix and Mysql

Hello everybody,

I've just installed Virtualmin on an existings Webmin server (already configured as antispam server for many domains).

My postfix installation uses Mysql as storage for aliases, domains, ...

After installing Virtualmin, I've got an error : My virtual alias maps didn't be compatible with Virualmin. So, on the "Features and Plugins" page, I've unchecked these elements :

• postfix
• bind
• statistics
• mysql

I just want users on Virtualmin to manages thier static websites.

Now, when I go to the "System Information" page, I've got this error :

SQL query failed : You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ' from where 1 = 1' at line 1

Can you tell me if my installation is good and why I've got this error ?

Thanks a lot

Regards,
