my problem was .htaccess file & my redirects

Code
# Redirect non-www URLs to WWW

RewriteCond %{HTTP_HOST} ^yourdomain.com$
RewriteRule ^(.*) http://www.yourdomain.com/$1 [QSA,L,R=301]

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^/?$ http://www.yourdomain.com/forum/ubbthreads.php [R=301,L]

RewriteCond %{HTTP_HOST} ^.*$
RewriteRule ^forum/ubbthreads.php/?$ http://www.yourdomain.com/forum/ubbthreads.php [R=301,L]

SecFilterEngine Off
SecFilterScanPOST Off
I listed my htaccess well only what has to do with the board wink
for you I think just uncheck the HTTP Referrer Check in your config file will work
