Upgrading Drupal

I recently upgraded my Drupal site from 4.1 to 4.3.2 (yes I know it's out of date, it's the one in Debian testing).

I have configured it to allow anonymous users comment posting without approval. Anonymous comments, however, don't seem to be working, while comments from logged-in users are. As an anonymous user, you can preview your comment, and it looks fine, but when you post the comment, when you return to the front page, the comments count for that story has increased by one, but the comment isn't there!

I have upgraded a 4.3.2 installation to 4.4.1 ; upgrade went relatively smoothly. However, about in 24 hours after the upgrade, I started getting messages from the cron execution, like this:

user error: Unknown column 'timestamp' in 'where clause'
query: SELECT * FROM feed WHERE timestamp + refresh < 1085378403 in /home/mbravo/www/yoshinkan.spb.ru/includes/database.mysql.inc on line 97.

When I checked the sources to aggregator.module and compared them with my database structure, sure enough, there were differences. There were no fields like timestamp, or author in the "feed" table. I checked database/mysql sources, and there were no such fields in that table either. At the same time, the feeds I have defined for syndication seem to be updating.

What am I missing with this error, and how do I fix it correctly?

Thank you ever so much for useful advice.

I'm trying to upgrade a site that is 4.3 to 4.4.1 and followed the instructions (backed-up, overwrote the files, logged in, updated the conf.php, did the database system table modification) for upgrade (and I have done upgrades on other sites). This time around when I clicked on the "run database upgrade script" I get the following error:

Warning: main(DB.php): failed to open stream: No such file or directory in /home/virtual/site4/fst/var/www/html/tiva/includes/database.pear.inc on line 4

To setup a blogger API, I am using w.blogger,
for server side,
I ticked "Enable users to post using applications that support XML-RPC blog APIs" checkbox under administer/configuration/modules.
then I tried to find "Access Blogger API" checkbox under administer/accounts/permissions but I couldn't find
Do you know where it is or ....

After upgrading to 4.4.1 I am getting this error. I think it is something in my template?

Notice: [XTemplate] parse: blockname [header.title] does not exist in /home/somesite/public_html/themes/xtemplate/xtemplate.inc on line 418

I've upgraded to 4.4.1 the other day and noticed that my site cloud admin page is no longer working. I've serched this site and haven't found anyone with the same problem. What am I missing?

Here is the error returned when I attempt to access the admin page:

Fatal error: Call to undefined function: table() in /home/httpd/htdocs/bs/modules/cloud.module on line 146
