Help! My site is broken, all links go to 404 page now.

Drupal: 6.3
Gallery: 2.3 rc1
PHP: 5.2

---
I installed gallery and got it configured the way I wanted to, and then downloaded the gallery module for Drupal.

Going through the set up sections, after I enabled the "URL" rewrite, my entire page stopped working. I can't access /admin, or any other part of the site.

I know it's because of what was added to the top of my .htaccess in my web root directory, because once I commented it out, my site started working again.

However, the URL rewrites are an important part of why I chose to go with Gallery2, so I'd like to try to get whatever the problem is solved.

Here's what was added to the top of the .htaccess:

# BEGIN Url Rewrite section

I'm not against tinkering with things to get it working, and browsing around it seems other people have had similar issues (though perhaps not as severe as mine), so any help would be appreciated.

It appears this is what was also added to my .htaccess file in the 'g' (gallery2) directory

My site crashed as well. All except the frontpage now goes to Error 404 page. Nothing works on my site anymore and I can't access the admin area or anything. Only thing different from you is that it seems my .htaccess file is totally gone.

Did you get a solution to your problem here? I need help to get my site back up again

Thank you, that really saved my day!
