Upgrading Drupal

I have upgraded to the latest security fix on nodeword and all my existing meta tags have been destroyed and I cannot add any new ones. My fault or a broken upgrade?

I upgraded our installation from 6.13 to 6.14 today with fewer mishaps than usual ;)

The only problem I can see so far is that the status report says the files directory is missing:

"File system Not writable
The directory files does not exist. You may need to set the correct directory at the file system settings page or change the current directory's permissions so that it is writable. "

Hmmm. The files directory is in .../sites/default, where it's always been. Permissions on the directory are 777.

Any ideas? Never come across this one before.

Ok never mind.. Misred.

Hi,
I´m upgrading from 6.10 to 6.14 and running the update.php file, and for a while after that I had the white screen of death.

Eventually, after repeating the upgrade attempts a few times, I got an error message saying :-

Error: Unable to use the MySQLi database because the MySQLi extension for PHP is not installed

on each page I attempted to access on my website.

So, I modified the settings.php file to change the line :-

$db_url = 'mysqli://username:password@localhost/databasename';

My name is Kunal
I want to upgrade my existing drupal 5x site to 6x but i am facing some problems here ..

2. I want to test drupal 6x the same in my localhost but the database i have backedup is not effecting it gives error..
3. I have also installed the existing drupal 5x site and database in my phpmyadmin it works fine..
4. Now how can i restore the same 5x database to the drupal 6x ...in my localhost ( i am using ubuntu linux, apache2, Php5, MySql )

Code changes to includes/database.mysql.inc in v. 5.20 causes my up-until-now stable installation of Drupal to return the following when attempting to use the Search function:
