Upgrading Drupal

I very recently upgraded from 5.20 to 6.14. For some reason, authenticated users can't switch themes because "Theme Configuration" is missing from My Account-->Edit-->Account. It is there for moderators and administrators. I can't seem to find any place that controls permissions for the authenticated users to switch themes. Previously, switching themes was available to all authenticated users without permissions being set--as far as I was aware. Are there permissions that control if this section shows up or not? Thanks in advance.

I'm planning to build a website but I'm curious about upgrading from 6 to 7.

I read upgrading guide.
I think it looks simple. run update.php and all was done.

but i am curious about a few thing. After I upgrade successfully, can I face problems because of differences between 6 and 7

instead of upgrading, to recreate a website with newer version is better?

Does the order matter? Should I update the modules first, then the core or vice versa? Which is the preferred method (and why)? Thanks for any insight.

Hi all, and thanks for your attention,

With Drupal 6.13 I did have a session bug who continually disconnect the admin user after his connection (or maybe I did something wrong).
This cause me to do a not-so-clean update.php with Drupal 6.14, with settings.php on "$update_free_access = TRUE;", and contributed modules and themes not disabled ....

I am upgrading a site and I am getting a weird error in the update.php screen. It reads, "userreference module can not be updated. Its schema version is 0. Updates up to and including 4 have been removed in this release. In order to update userreference module, you will first need to upgrade to the last version in which these updates were available."

I am up grading... so what upgrade is it referring to?

Thanks,

Hello all,

For some absurd reason, I placed drupal 6.12 in the sites/all/modules folder when I tried to update the drupal version. Now, though, when I try to take it out, I always get an error message and I can't even update to the newest version (what is it, drupal 6.14?). I cant even use some core modules like poll either. Are there any ideas on how to properly install drupal again?

Thanks,
