我的apache错误日志充满了这个，我不知道是什么问题。这是我的.htaccess文件。有人可以帮帮我吗？
RewriteEngine on
# check that the request url is neither a file nor a directory
RewriteRule ^panel/?$ panel/ [NC,L]
RewriteRule ^([A-Za-z0-9-]+)/?$ app.php?slug=$1 [NC,L]
RewriteRule ^([A-Za-z0-9-]+)/index/([A-Za-z0-9-]+)/?$ app.php?slug=$1&index=$2 [NC,L]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule \.(gif|jpg|png|bmp) /images/default.jpg [NC,L]
我有另一个重定向到此的子域名。和htaccess：
RewriteEngine on
RewriteRule ^(.*)$ http://ro.sughy.com/$1 [R=301,L]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} !-f
RewriteRule \.(gif|jpg|png|bmp) /images/default.jpg [NC,L]
