vBSEO + Photopost = No Photo? (blank Page)

Hi,
installed vBSEO yesterday, everything seemed to work fine. Now i took a look at a Photo of my Photopost-Gallery: ( http://www.vampster.com/photopost/sh...php?photo=2168 for example) and got a blank page.

If i set vBSEO not active at vBulletin-adminCP, all works fine. If i switch it on, "...showphoto.php?..." is a blank page.

Also the hint i found here, placing a .htaccess with "RewriteEngine off" into photopost dircetory, has no effect.

I use vB 3.7.2 and PhotoPost 6.11
On the Server runs php4 and php3 - read somewhere here that this maybe causes a problem?

vB is here: www.vampster.com/forum/
Photopost: www.vampster.com/photopost/

my .htaccess in forum/ looks like this:

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 /forum/
#RewriteCond %{HTTP_HOST} !^www\.vampster\.com
#RewriteRule (.*) http://www.vampster.com/forum/$1 [L,R=301]
RewriteRule ^((urllist|sitemap_).*\.(xml|txt)(\.gz)?)$ 
vbseo_sitemap/vbseo_getsitemap.php?sitemap=$1 [L]
RewriteCond %{REQUEST_URI} !(admincp/|modcp/|cron)
RewriteRule ^((archive/)?(.*\.php(/.*)?)?)$ 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]

can you please help?
thanks, markus

okay, found it out by myself
Links to Photopost Gallery are blank pages? helped. don't know what exactly happens with this other code but now it works correctly.

Glad to see that you found a solution.
