.htaccess mod_rewrite issues

I have installed AV arcade and it seems like after turning on the SEO URLs function, all of the pages except the homepage return 404 error.

Here's how the htaccess file looks:

RewriteEngine on
RewriteRule ^view/([0-9]+)/([0-9a-zA-Z?-]+) index.php?task=view&id=$1&name=$2 [L]
RewriteRule ^cat/([0-9]+)?/([0-9a-zA-Z?-]+)/p([0-9]+) index.php?task=category&id=$1&name=$2&page=$3 [L]
RewriteRule ^profile/([0-9]+)?/([0-9a-zA-Z?-]+) index.php?task=profile&id=$1&name=$2 [L]
RewriteRule ^profile/comments/([0-9]+)?/([0-9a-zA-Z?-]+) index.php?task=users_comments&id=$1&name=$2 [L]
RewriteRule ^page/([0-9]+) index.php?task=view_page&id=$1 [L]
RewriteRule ^task/register index.php?task=register [L]
RewriteRule ^task/lost-password index.php?task=lost_pass [L]
RewriteRule ^task/links index.php?task=links [L]
RewriteRule ^task/allnews index.php?task=news [L]
RewriteRule ^task/members index.php?task=member_list [L]
RewriteRule ^task/messages index.php?task=messages [L]
RewriteRule ^task/search index.php?task=search [L]
RewriteRule ^task/news/item/([0-9]+)/([0-9a-zA-Z?-]+) index.php?task=view_news&id=$1 [L]
RewriteRule ^task/messages index.php?task=messages [L]

Code (ApacheConf):

The host supports mod_rewrite so it can not be that. What may cause those 404s?

 

check your error log of your server. see which pages gave 404 error? this will help to know where mod rewrite is looking

 

i suggest you set the correct RewriteBase: http://httpd.apache.org/docs/1.3/mod/mod_rewrite.html#RewriteBase

good luck... failing that you may need a firefox http headers plugin so you can track the redirect and see where it goes wrong.
