Upgrading Drupal

I'm in the process of upgrading a site built on Drupal 6 with some new functions built on a separated server running Drupal 7. The existing users on the Drupal 6 site should be able to use the functions on the new Drupal 7 server. I followed the instructions at https://drupal.org/node/291373, and configured the setting.php to share following tables: users, sessions, role, and authmap, which are copied from the Drupal 6 site and in a shared database.

This article: SA-CORE-2013-003 - Drupal core - Multiple vulnerabilities suggests to put

Options None
Options +FollowSymLinks

in your .htaccess files in both private and public (sites/default/files/) files directory.

If I put that in my public files directory, there is no theme on my site.

What am I missing?

I am having 'fun' installing the colorbox module for over two hours!!! Below are the warnings I get. Those warnings are warming my heart, big time. :(

Hi to all,
i'm trying to set a particular cookie after a user login but i'm having trouble because i'm also using varnish.

So i've tryed setting the cookie in the hook_init or in the hook_user_login but nothing.
That's because all the pages are cached by varnish so when the user is redirected after the login to a page this page is cached.

If i go in a page non cached the hook_init of my module set the cookie rightly.

I have updated my drupal 7.16 to 7.24. I have used the multi-image field in the custom form using function field_attach_form. Now, My problem is the image thumbnail which is generated on uploading the image is not coming. But if I used that field instead of custom form in admin node/%/edit/ page then it is coming. It is also not coming on amazon server but on my local system it is working fine. Please help on this.

I need to update my site to the newest security update but I do not know where on my server the files are? I am using Cyber Duck to access my server.

Thanks in advance!
