Upgrading Drupal

I upgraded to Drupal 4.6.1, overwriting the existing 4.6 files with the new ones, then ran the update.php script as instructed.

After doing so, I'm seeing this

div>\n";
  }

  $output .= " </div>\n";
  $output .= "</div>\n";

  return $output;
}

?>

at the beginning of the source code for every page. The browser renders this as well. This problem is showing up in my custom theme and in the stock bluemarine theme that came with the 4.6.1 distribution.

Is it right that the only answer when running update.php from 4.6.0 to 4.6.1 is as follows:

<strong>2005-05-06

2005-05-07</strong>

ALTER TABLE {locales_source} CHANGE location location varchar(255) NOT NULL default '' 
OK

That means that main changes are in the files and not in the database?

I am running 4.6.1 and I need the ability to display news feeds on a site, however there are far too many irrelevant stories without the ability to filter based on keywords.

The "news page" module seemed to do what I want but it is no longer available since Drupal 4.6 is not compatible with existing modules.

Does 4.6 have a filtering ability that I haven't found? It would seem that this is a primary function of a news aggregator (otherwise its just a pile of unsorted and unfiltered information).

I preserved my files/* sub-directories, such as /tmp and /images, and the content contained in them, when I upgraded from Drupal 4.6.0 to 4.6.1.

But now, when I open my Administer > settings pages, I get error messages saying BOTH that the sub-directories do not exist AND warning messages that they cannot be created, e.g.

warning: mkdir(tmp): Permission denied in ... /httpdocs/includes/file.inc on line 86.

The content in those sub-directories is still displayed on my site. How can the administration modules be made to detect the existing content?

I upgraded from 4.4 to 4.6 without much problem. In the 4.4 site I had many news feeds displayed in blocks on the front page. After upgrading, I set about categorizing the news feeds. I added some categories that weren't there before. Then, I went to the administration menu, clicked "blocks" - and got the following error message:

So I instaled the taxonomy patch for the taxonomy_access module, however it didn't work so I decided to revert it to the .orig file after deactivating the module.

Now after I did that, I am unable to view terms. Instead I get a blank page.
ie> http://www.0reality.com/taxonomy/term/62

Any idea what went wrong and how to fix this? Or should I just backup the database, reinstall drupal, reinstall the modules I need and reinstate the database data?
