Upgrading Drupal

In brief: I can't see any of my images in my upgraded site. I suspect it is because the url is looking for 'system/files/images/img.jpg'.

Background: I am in the process of upgrading my 4.7.5 site to drupal 5. In my 4.7 site, I use image.module extensively. All file uploads were set to PRIVATE. So, the 'files' folder was here: root/username/www/files/, with 'images' in 'files', and my drupal site was also in home/username/www.

In drupal 5, I am doing a multisite install. So, the drupal core is here: root/username/www/stuff. The site I am upgrading is here: root/username/www/sites/snq.domain.com, 'snq' is being redirected to this folder. The 'files' folder is in 'root/username/www/sites/snq.domain.com/files' and according to the admin, it is present and readable. All images are there as well.

However...

When I go to visit an image, the url is this: http://snq.domain.com/system/files/images/img.jpg, and a 'page not found' error is returned. After some reading, this appears to be b/c I have set my file settings to PRIVATE. However, I did not change this from drupal 4.7.

So, do I have my 'files' folder in the right place (the 'sites/snq.domain.com/files' folder)?
Do I need to put it ABOVE www (so, 'root/username/)? If I do this, what will distinguish it from other multisite running on the same account?

Hello,

I recently upgraded from 4.7 to 5.1. After tweaking a bit to fix some DB errors and warnings, it now works great EXCEPT CAS login for a new user.

When I login with a new user, it gives me following warnings:

Our administratior recently upgraded from 4.6.? to 5.0. We had several flexinode events in the database at the time. Now, when I attempt to access the old event node, I get the error:
warning: call_user_func_array() [function.call-user-func-array]: First argumented is expected to be a valid callback, 'flexinode-4_node_form' was given in /usr/share/drupal-5.0/includes/form.inc on line 217.

How can I delete the old flexinode? As I understand it, flexinode has been dropped from Drupal5.

I have gone through every option I can think of, but I can't figure out how to get even the basic blocks to display in 5.1 after an upgrade from 4.7.*. Navigation, User Login, any of them - they simply won't display, no matter where I choose to display them.

It also doesn't matter what theme I choose. Garland, a new downloaded one - they all have the same result.

Has anyone run into this issue before? Do I need to manually clear some tables?

Please excuse me if I posted to the wrong group. Please tell me which group would be better.
Also, please excuse me if i am wrong to how to do the following. I need help and guidance.

We are seriously in an isuue that how to manage the profile fields associated with the roles? We have seen examples from - drupal.org/node/53103 but that is for drupal 4.6 or 4.7 version.We need it for drupal 5.x

I recently updated to 5.1, and it's been a huge hassle. I'm using the chameleon theme, but my time stamps don't show with this theme. They do show with other themes. Is there a way to show the time stamps using 5.1 and chameleon? (Note: I've already checked by global settings, etc.) Here's my site, http://okiefunk.com. Unless I'm missing something obvious, my theme selection is quite limited using 5.1.
