Upgrading Drupal

We just upgraded one of our sites from 4.6.5 > 4.6.6 and the menus we added no longer show up. Although the block title still shows, the menu items are no longer there.

We removed all menu items and menus, then started over with the same results.

Menu titles show but the menu items do not.

FC2/Plesk 7.5.4 - Apache 2.16.x, mod_security, grsec

I just updated to the latest verson drupal 4.7bata6 yesterday, and here the problem appears.

Whenever I create new posts (via 'page', 'blog entry' or 'story'..), a warning appears:
"warning: Invalid argument supplied for foreach() in D:\hshome\mysite.com\modules\upload.module on line 432."

Although the warning appears, all posts seem not to be affected.

Will it be another bug or I am experienced it alone?

user warning: Table 'learnand_drupal.file_revisions' doesn't exist query: SELECT * FROM files f INNER JOIN file_revisions r ON f.fid = r.fid WHERE r.vid = 378 in /home/learnand/public_html/includes/database.mysql.inc on line 120.

Can I put this in with a SQL query? If so where could I find that? Thanks.

Hello!

Hi, I recently ugraded to Drupal 4.6.6 from 4.6.3 and noticed that items in the Navigation menu had magically disappeared. The funny thing is they appear active in the menus page, in the admin. Can anyone help solve this problem?

Your help would be much appreciated.

I'm not really sure what's going on here. I have a Drupal 4.6.5 multisite installation with some shared tables, but I'm looking at upgrading to 4.7. Why? Because there are some new modules, and more importantly, improved/fixed versions of other modules that only work with 4.7, and that functionality is important to me. But I have a couple questions:

1. How different IS 4.7? Complete re-write? How backwards-compatible is it with modules that were written for 4.6.x and haven't been developed for 4.7? If it's completely different and none of the old modules will work... is this going to happen with every bloody release? I used to use PHP-Nuke and while a couple version upgrades broke some modules, the vast majority of modules still worked when a new version came out. Themes likewise.
2. What on earth is with the different versions? What is the difference between 4.7.0-beta.x, 4.7.x, and CVS? I thought software tended to have the-stable-version-that-is-released, and the-unstable-version-that-is-coming. But Drupal seems to have at least 5 different versions available for download, and a hodge-podge of modules for each. Will a CVS module work with, say, 4.7.x?
3. Am I going to have a lot of trouble updating all my database tables with my multisite shared-table installation?

It's all very confusing. It would be nice if someone could clear this up. If there is a page in the handbook about all this, I couldn't find it. There should be. Something like:
