config problems

Hello,
I upgraded to version 2.2.0 without any problems, but when I now go to the config file I get a blank white page...permissions for the file are correct..what have I done wrong?

Thanks

what i would do to find the prob would..

- check if plugin was installed and reinstalled, then check vb config file
- use old config file if works then i know something is deff wrong with new version

Actually I explained this wrong...when I go to vbseocp.php it redirects me to my forum home page, not the seo config login.

try adding

RewriteCond %{REQUEST_FILENAME} !vbseo_sitemap/

to the .htaccess , worked for me.
