عدم نمایش زیر منو ها در جوملا 2.5.11

[Polikopi]

با سلام من یک سایت در جوملا ایجاد کرده ام [مهمان/کاربر گرامی برای دیدن لینک ها ابتدا باید عضو سایت شوید و لاگین کنید برای ثبت نام اینجا کلیک کنید] صفحه اصلی باز میشه اما هنگام کلیک بر روی زیر منو ها صفحه ای باز میشه با این پیغام
Not Found

The requested URL /محصولات/slm was not found on this server.

Additionally, a 404 Not Found error was encountered while trying to use an ErrorDocument to handle the request.

قبلا این مشکل را نداشتم .کسی میتونه برطرف کنه .ممنون

سلام

وجود فایل htaccess. رو بررسی کنید.

[Polikopi]

وقتی در قسمت مدیریت می روم یک پیام شل با این صورت ظاهر میشه که هیچ کاری نمی تونم بکنم. در سی پنل بازش کردم داخلش این را نوشته حالا چه باید کنم
<IfModule mod_security.c>
SecFilterEngine Off
SecFilterScanPOST Off
</IfModule>

داخل فایل .htaccess باید اطلاعات زیر وجود داشته باشه:

# The line just below this section: 'Options +FollowSymLinks' may cause problems

# be set by your server administrator in a way that dissallows changing it in

## Can be commented out if causes errors, see notes above.
Options +FollowSymLinks

## Mod_rewrite in use.

RewriteEngine On

## Begin - Rewrite rules to block out some common exploits.
# If you experience problems on your site block out the operations listed below
# This attempts to block the most common type of exploit `attempts` to Joomla!
#
# Block out any script trying to base64_encode data within the URL.
RewriteCond %{QUERY_STRING} base64_encode[^(]*\([^)]*\) [OR]
# Block out any script that includes a <script> tag in URL.
RewriteCond %{QUERY_STRING} (<|%3C)([^s]*s)+cript.*(>|%3E) [NC,OR]
# Block out any script trying to set a PHP GLOBALS variable via URL.
RewriteCond %{QUERY_STRING} GLOBALS(=|\[|\%[0-9A-Z]{0,2}) [OR]
# Block out any script trying to modify a _REQUEST variable via URL.
RewriteCond %{QUERY_STRING} _REQUEST(=|\[|\%[0-9A-Z]{0,2})
# Return 403 Forbidden header and show the content of the root homepage
RewriteRule .* index.php [F]
#
## End - Rewrite rules to block out some common exploits.

## Begin - Custom redirects
#
# If you need to redirect some pages, or set a canonical non-www to
# www redirect (or vice versa), place that code here. Ensure those
# redirects use the correct RewriteRule syntax and the [R=301,L] flags.

## End - Custom redirects

# Uncomment following line if your webserver's URL
# is not directly related to physical file paths.
