404 - .htaccess problem

After upgrading to 3.3.0 I started to have 404 errors in many folders of my site. My forum and homepage works correctly (except albums not showing photos after upgrade) but when I try to run other files in other folders, always get a 404 error. I've tried this but nothing changed.

The .htaccess in my root and forum folders are like this (my admin and mod folders are named admin and mod, not admincp and modcp):

Code:

# Comment the following line (add '#' at the beginning)
# to disable mod_rewrite functions.
# Please note: you still need to disable the hack in
# the vBSEO control panel to stop url rewrites.
RewriteEngine On

# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root vB folder (i.e. RewriteBase /forums/)
#RewriteBase /

#RewriteCond %{HTTP_HOST} !^www\.dipsizkuyu\.net
#RewriteRule (.*) http://www.dipsizkuyu.net/forum/$1 [L,R=301]

RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{QUERY_STRING} !vbseourl=
RewriteCond %{REQUEST_URI} !(admincp/|modcp/|chat|cron)
RewriteRule ^(.*\.php(/.*)?)$ vbseo.php?vbseourl=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !\.(jpg|gif)$
RewriteRule ^(archive/.*)$ vbseo.php?vbseourl=$1 [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !^(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php?vbseourl=$1 [L,QSA]

<IfModule mod_security.c>
   SecFilterEngine Off
   SecFilterScanPOST Off
</IfModule>

<Files 403.shtml>
order allow,deny
allow from all
</Files>

vBSEO .htaccess file has been updated. Please use the .htaccess file that comes with vBSEO 3.3.0 package.

This is it, I've only changed admin/mod cp paths and added mod security part.

vBSEO 3.3.0 .htaccess content is as following

Code:

# Comment the following line (add '#' at the beginning)
# to disable mod_rewrite functions.
# Please note: you still need to disable the hack in
# the vBSEO control panel to stop url rewrites.
RewriteEngine On

# Some servers require the Rewritebase directive to be
# enabled (remove '#' at the beginning to activate)
# Please note: when enabled, you must include the path
# to your root vB folder (i.e. RewriteBase /forums/)
#RewriteBase /

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

RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]

RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron|vbseo_sitemap)
RewriteRule ^((archive/)?(.*\.php(/.*)?))$ vbseo.php [L,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !/(admincp|modcp|clientscript|cpstyles|images)/
RewriteRule ^(.+)$ vbseo.php [L,QSA]

I've changed it to this (except forum path) but the problem still exists.

If you have international characters within your album titles , make sure album rewrites include album_id

Thanks for this tip, but there is one more thing. I've uploaded some files to a folder named testvb, I was planning to install a test forum but when I try to run files from browser, I always get a 404 error.

You need to create a support ticket and request a test license. vBSEO will only run on registered domain.

No, it's on the same domain. What I'm doing it to try to install a test forum on my vbseo registered domain.

Even it is on the same domain , you'll need a test license.
