Upgrading Drupal

I've been diligently following along the great video on upgrading Drupal from Lullabot, and have come across a snag. I successfully backed up the database files (deliciously easy.) However, I'm having problems with the next step of backing up my Drupal 4.7 files.

As the video instructs, I open up a command line and use the "cd" command to get to the folder "directly above" my Drupal folder, that being

C:\apache2triad\htdocs

Just upgraded a site to 5.0 and have found the collapsible fieldsets aren't working. Anyone else encountered (and more importantly, fixed) this?

I post this so that it might be of use to someone who may also be having difficulties with their upgrade.

After upgrading my site, everything worked OK... most of the time. Every once in a while, I saw a php error about a duplicate ID or something in the watchdog or cache table, but it wasn't often enough to figure out the cause.

Then I noticed that when nodes were updated, their url alias disappeared, pathauto wansn't creating new aliases, and even paths that I explicitely typed into the node edit form weren't saved.

Just upgrade a site from 4.6.8 to 4.7.5 to 5.0. I did extensive testing at 4.7.5 and had no issues. After upgrading to 5.0, I'm having a weird issue where the links for collapsible fieldsets on node edit forms are broken when I use https connections. Everything is fine when using http connections.

This problem only affects the node edit forms and happens with all themes. It does not affect collapsible fieldsets on admin pages, however. I'm having this problem with and without contributed modules enabled. The only contributed modules I'm currently running are:

www.111mysite.com/?q=admin/module

link doesnt work when i put cck files into modules directory so i cannot enable CCK. but when i remove files, admin/module link cleanly works

I upgrade from 4.7.5 to 5.x. When i try to create a node (page, blog, forum,...etc.) i get pop pup from IE: IE can't open site. Some times When i go back (IE navigation menu) a get the interface to create the node and in others no. I have fckeditor instaled and working fine.
I apreciate any help. Thanks
