Upgrading Drupal

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

I have a 4.7 site where I used to CCK to create some content types with a few fields that 4.7 did not support. I now want to upgrade that site to 5.0.

Assuming that the fields I created are supported by the various CCK add-ons for 5.0, what kind of trouble might I have upgrading the site?

Will the custom content types I created in 4.7 automatically port to 5.0?

What will happen when I try to display a node using one of those custom content types if there's a field in the node that 5.0 does not support?

Thank you!

I upgraded to drupal 4.7.5 and it runs fine if I disable gmap. If I enable gmap, I get this warning:

user warning: Unknown column 'eid' in 'where clause' query: SELECT * FROM location WHERE eid=1 AND type='user' in /home/user/html/site/includes/database.mysql.inc on line 121.

I googled the message and all I turned up are a couple of sites apparently having the same trouble as me.

any ideas on where I can look to get rid of this? update.php doesn't show any updates pending.
