Upgrading Drupal

I need help. I don't know what happened but I can't run the upgrade script anymore.

When I click on "run upgrade script" I get the following errors on the page that shows you what it will update and the "update" button.

Notice: Undefined variable: updates in httpdocs/includes/install.inc on line 39

I know RTFM but I have looked everywhere and cannot find an answer to this problem. Here is the problem:
*Upgrading form 4.6.8 to 4.7.3
*PHP 5.1
*MySQL 5.0

The error, I know it is common but I have reinstalled the themes in 4.6.8, made sure that set to bluemarine and still get this error:
user warning: Unknown column 'theme' in 'where clause' query: SELECT * FROM blocks WHERE theme = 'bluemarine' AND status = 1 ORDER BY region, weight, module in /var/www/html/drupal47/includes/database.mysql.inc on line 120.

Can not as Admin access some settings after upgrade to 4.7.2
i am Not able to enter and set permissions as Admin, Also I find that I can not allocate Admin to other users on site as the Admin feature is not showing in users Accounts including mine.
I have turned off firewalls and still not able to enter this page,But i can enter other admin areas.
Error log shows "access denied admin/access/permissions denied access"
Page shows "You are not authorized to access this page".

Can any one help me how to resolve this issue

Hi Drupalers,

I have just upgraded to the latest Flexinode release, and although I too can add fields to my content types, and also create and submit the forms, unfortunately, although the data is in the database, it does not get displayed when trying to view it, it only displays the title.

Am I missing something ?

Thanks in advance.

Good morning,

I would like to make an upgrade from feedback module, but I don't understand what the INSTALL file say :

Hello,

I've upgrade our Drupal version to 4.7.3, and I would like to know how I can upgrade my old weblink?

The last weblinks (version 4.7.3) install file say I must :

"Upgrade
------------
As if this version (08 May 2005), a new database scheme is used for the weblinks. You will thus need to upgrade your old database, if you want to use the weblink module on 4.6.

1) BACKUP: Back up your data! Really. Do not skip this one. No really: don't! Yes, even you should backup. Allright, you stubborn, then don't, but be prepared for dataloss.
