Search Engine Optimization (SEO) Enable URL-Rewrite

when clicking register link, user directed tohttp://beta.********.org/register/ but the results is 404: Page Not Found

well, it's because i activated Enable URL-Rewrite, then not adding this code to htaccess:

<IfModule mod_rewrite.c> RewriteEngine On  RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?$1 [L,QSA]</IfModule>

the tutorial link (in ACP) is broken http://beta.*******.org/acp/dereferrer.php?url=https%3A%2F%2Fblog.woltlab.com%2Fentry%2F67-setting-up-user-friendly-urls%2F , so i have to google it myself.

Now, the problem is url Forum

when clicking one of forum (http://beta.********.org/forum/board/2-diskusi-dan-feedback/)

then come the error

Page Not FoundSorry, but the page you are looking for has not been found. Try checking the URL for errors, then hit the refresh button on your browser.
Back to previous page.

I can provide admin account if staff want to investigate.

ok, i am really a newbie to woltlab, so i have to add this code to .htaccess in /forum directory too?

<IfModule mod_rewrite.c> RewriteEngine On  RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?$1 [L,QSA]</IfModule>

Then, beside /root directory and /forum directory, is there more directories?

after adding mod_rewrite code in htaccess of /root directory and /forum directory, unfortunately there are still pages that can not be viewed (return no found error). How can i solve this?

now i see, not all pages can be access direclty, for example, for creating thread, you have to add forum number (2), like this one:

http://beta.hondabrio.org/forum/thread-add/2

not a bug maybe.
