Can't access gallery site admin...

Trying to configure the URL rewrite rules in gallery2 messed something up. (Embedded in Drupal 6.11). Now whenever I click on 'Site Admin' in gallery it goes to the Drupal administration page. It does this even if I access in standalone mode.

embedded .htaccess

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /gallery2/
    RewriteCond %{REQUEST_FILENAME} -f [OR]
    RewriteCond %{REQUEST_FILENAME} -d [OR]
    RewriteCond %{REQUEST_FILENAME} gallery\_remote2\.php
    RewriteCond %{REQUEST_URI} !/gallery2/main\.php$
    RewriteRule .   -   [L]
    RewriteCond %{THE_REQUEST} /gallery/v/([^?]+)(\?.|\ .)
    RewriteCond %{REQUEST_URI} !/gallery2/main\.php$
    RewriteRule .   /gallery2/main.php?g2_path=%1   [QSA,L]
</IfModule>

drupal .htaccess

<FilesMatch "\.(engine|inc|info|install|module|profile|test|po|sh|.*sql|theme|tpl(\.php)?|xtmpl|svn-base)$|^(code-style\.pl|Entries.*|Repository|Root|Tag|Template|all-wcprops|entries|format)$">

Any ideas?
