Joomla Y Vbseo

Muy buenas :cool: a ver si alguién me saca de mis dudas existenciales.
Primero en el dominio principal tengo instalado Joomla y el modulo URLS amigables
En joomla todo funciona a la perfección.
Pero despues en el subdirectorio nodo he instalado el vbulletin y las seo y las seo no funcionan o pirulan.

He puesto el .htaccess tal como indica y nada no pirula nada y las instrucciones estaan bién claritas y faciles por lo que creo es un conflicto entre el .htaccess en el directorio principal joomla COPIO AQUI MI .HTACCESS DE JOOMLA Y MI .HTACCESS de vbulletin

A la espera de un benefactor un saludo

# READ THIS COMPLETELY IF YOU CHOOSE TO USE THIS FILE

# The line just below this section: 'Options FollowSymLinks' may cause problems
# with some server configurations. It is required for use of mod_rewrite, but may already
# be set by your server administrator in a way that dissallows changing it in
# your .htaccess file. If using it causes your server to error out, comment it out (add # to
# beginning of line), reload your site in your browser and test your sef url's. If they work,
# it has been set by your server administrator and you do not need it set here.
#
# Only use one of the two SEF sections that follow. Lines that can be uncommented
# (and thus used) have only one #. Lines with two #'s should not be uncommented
# In the section that you don't use, all lines should start with #
#
# For Standard SEF, use the standard SEF section. You can comment out
# all of the RewriteCond lines and reduce your server's load if you
# don't have directories in your root named 'component' or 'content'
#
# If you are using a 3rd Party SEF or the Core SEF solution
# uncomment all of the lines in the '3rd Party or Core SEF' section

##### SOLVING PROBLEMS WITH COMPONENT URL's that don't work #####
# SPECIAL NOTE FOR SMF USERS WHEN SMF IS INTEGRATED AND BRIDGED

#
# In both the 'Standard SEF', and '3rd Party or Core SEF' sections the line:
# RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR] ##optional - see notes##
# May need to be uncommented. If you are running your Joomla/Mambo from
# a subdirectory the name of the subdirectory will need to be inserted into this
# line. For example, if your Joomla/Mambo is in a subdirectory called '/test/',
# change this:
# RewriteCond %{REQUEST_URI} ^(/component/option,com) [NC,OR] ##optional - see notes##
# to this:
# RewriteCond %{REQUEST_URI} ^(/test/component/option,com) [NC,OR] ##optional - see notes##
