[Typo3] sr_feuser_register -> Warnings

[Guillaume JULLIEN]

Hi,

When I use the sr_feuser_register extension in a page, I get the 
following messages in the FrontEnd :

***
Unknown column 'lg_country_iso_2' in 'field list'
Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL 
result resource in 
/home/ceapaves/www/typo3conf/ext/sr_static_info/pi1/class.tx_srstaticinfo_pi1.php 
on line 363

Warning: Cannot modify header information - headers already sent by 
(output started at 
/home/ceapaves/www/typo3conf/ext/sr_static_info/pi1/class.tx_srstaticinfo_pi1.php:362) 
in /home/ceapaves/www/tslib/class.tslib_fe.php on line 2402
***

What should I do to avoid this ?
