modsecurity problems

Hello, ok i did have the issue with modsecurity and file uploads and edited .htaccess with

<IfModule mod_security.c>
<Files async-upload.php>
SecFilterEngine Off
SecFilterScanPOST Off
</Files>
</IfModule>

This cured issue but server has had modsecurity updated to and now the site fails to load at all with error log showing

[alert] [client 82.45.191.88] /hsphere/local/home/wwwuser/domain.com/.htaccess: SecFilterEngine not allowed here

if i comment out the above .htaccess entry site come back but again have image upload problems?

any ideas?

cheers
