can anyone help me out please?!!

Hi All,

I tried upgrading a copy of my Drupal 6 site to Drupal 7, and all the image nodes (of which we have thousands--images are probably the main content pieces of our site) are no longer available.

i don't know how i can explain my situation exactly. i am no developer or a geek. so i try to explain my problem so simple as i can.

how it have to work:

there are two urls and protocols.
http://normal.url.org/hcms
https://secure.url.org/hcms

to login into the drupal page, i will use ssl. to edit or create forum topics i will use normal http as authenticated user. to change user settings or administer the site i switch to ssl.

the post core update problem:
login via ssl works fine. switch to an defined non ssl site drop the login status or what ever. it looks like you are logged out. if you use the browser back button to go back you are also back in your session. ???
i run into this ssl problem after an core update to 6.20. before this update everything work as expected.
here my working(pre update) setting files.

apache sites-available files. *only the needed information witch non real urls

my.site.file

        RewriteCond %{REMOTE_HOST} !an.ip.add.res

        RewriteRule ^/hcms/(../)?(user|cart|admin) \
                 https://secure.url.org%{REQUEST_URI} [R=301,L]

my.secure.site.file

ProxyPass /hcms/ http://normal.url.org/hcms/
ProxyPassReverse /hcms/ http://normal.url.org/hcms/

Hello,
I'm using Drupal 6.x and the Secure Pages + Secure Pages Hijack Prevention modules on a server that supports both SSL and non-SSL connection to the same site.

Whenever I upgrade some of the installed modules the connection switches from HTTPS to plain HTTP. For example:

hi, i was tinkering around my theme's template.php in an effort to theme the site's primary links when something happened that has caused the condition where the theme's page.tpl.php is no longer being called.

i've reviewed this page:
http://drupal.org/node/505216

i've cleared the cache many times now. In phpMyAdmin, I've looked at the system table for the theme in question. I don't see anything wrong there.

Just upgraded from 6.14 to 6.20, also upgraded some modules since the site hadn't been touched in over a year. The backend admin menu works fine, but none of the links work on the frontend. They all come back with "Page Not Found". If I type in "node/3" the page appears, but the links on the site won't. Help.
