Upgrading Drupal

Folks,

We have a really strange problem with a medium size site that has been upgraded from a D6 to a D7 (7.10).
The upgrade was fairly easy (as easy as such processes can be), and the site is running as expected except for one pretty major thing:

No new menu items can be added.

And with adding menu items I don't mean creating menu items in user menus manually (that works), but having D7 itself add menu paths as a response to installing modules, creating content types and much more.

It simply doesn't happen!

If we add a new content type called test_type, we should get a new menu item under node/add, but we don't. The path node/add/test_type leads nowhere and checking the menu_links and menu_router table tells us that they don't exist.

Same thing if we activate a module, say Dashboard. Normally we'd get a new link to click in the admin menu and the path admin/dashboard should lead to the Dashboard, but neither works.

If we add a menu item to hook_menu in one of our own modules, say /testing_menus as a callback, which returns some sort of banal page content, I get a page not found when trying to reach /testing_menus.

We have tried many things: Flushing caches, running update, uninstalling and reinstalling modules, fiddling permissions. Nothing changes this behavior.

I upgraded from Drupal 6.19 to 6.22 and it went more smoothly than I thought it would have, except that the images that ImageCache is supposed to resize for all my news nodes aren't displaying, and Nivo Views Slider is also not displaying the images it's supposed to.

I'm not sure where to tackle this problem from since it's the first time I upgrade Drupal. I'm assuming this has something to do with ImageCache but I took a look there and it seems like all the settings seem ok.
How can I fix this, or at least begin to find out where I should start tackling the problem?

After upgrading to drupal 7.2, enabled Pathauto, then,

1. configured URL aliases settings as follows:

Administration » Configuration » Search and metadata » URL aliases
Verbose
Separator -
Leave case the same as source token values.

Maximum alias length 100
Maximum component length 100
Update action
Do nothing. Leave the old alias intact.

and, 2. URL aliases pattern made all null.

As the result, content URL made something like

mysite.com/content/[title]

Hello men !

Yesterday I have tryed updating my 6.22 drupal site.
I have followed the upgrade.txt file. SO i have disabled all "contrib" modules and set my theme as "garland".

Then i have replaced all 6.22 files and folders (except the "sites" folder) with the 7.10 ones.

If now I try oi reach: www.mysite.com/update.php, the system show me this error:

Hey everyone.

Basically to be blunt: I reformatted my PC and didn't back up my MySQL database.

I did however backup my www directory (local dev).I re-installed Wamp server and copied over my www directory.

Receiving this error:
PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'jeffreyguerra.semaphore' doesn't exist:

So my question is can I somehow restore the database from my backup www files?

Any idea?
