SEO

I'm trying to do the latest VBulletin upgrade..completely locked me out of any access to my forum. I'm thinking this has to do with some htaccess stuff I was working with here some time ago. I'm clueless on this stuff so any help would be appreciated. My forum is down so I'm desperate. Here's the error I get while attempting to run the upgrade script:

Warning: Cannot modify header information - headers already sent by (output started at /home/xxxx/public_html/forum/includes/config.php:1) in /home/xxxx/public_html/forum/install/upgrade.php on line 21

Warning: Cannot modify header information - headers already sent by (output started at /home/xxx/public_html/forum/includes/config.php:1) in /home/xxx/public_html/forum/install/upgrade.php on line 22

Warning: Cannot modify header information - headers already sent by (output started at /home/xxx/public_html/forum/includes/config.php:1) in /home/xxx/public_html/forum/includes/functions.php on line 2801

(Note, I xxx'd out my directory name)

Here is my htaccess file. Same with the xxx's

# 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 vBulletin folder (i.e. RewriteBase /forums/)
#RewriteBase /

RewriteCond %{HTTP_HOST} !^www\.xxxx\.com
RewriteRule (.*) http://www.xxxx.com/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]

Could this be my problem? I can't even access my admincp.

I checked for the space on line 1 of my config.php, it didn't have it.

rename the .htaccess file to htaccess.txt so that it has no bearing. That will eliminate htaccess as the culprit.

That said, i don't think that's the case... sounds like a php error.

A plugin, perhaps?

Thanks Briansol,

I renamed the htaccess file, and I disabled vBSEO. Forum works fine now...so the problem is either in htaccess or vBSEO. I suspect htaccess. Any clues on how to proceed?
