Upgrading Drupal

I am trying to upgrade from drupal 4.5.2 to the latest cvs release. I have removed the old drupal files, put in the new ones and made sure the old conf.php with the db settings is readable and in the same place as before. When I try and run the db upgrade script from the update.php page I get an error from php saying unable to connect to mysql via /var/lib/mysql/mysql.sock I have no idea why drupal suddenly can't find the db when using the old drupal with the same conf.php it finds it no problem.

in addition to not being able to see any of my static pages when i click on the links to go to them (they are still in the db and i can get to them by doing a search or putting their node id in the address window, but not their taxonomy number), i also get another error:

warning: sprintf(): Too few arguments in /home/selfeste/public_html/drupal/includes/database.inc on line 147.

user error: Query was empty
query: in /home/selfeste/public_html/drupal/includes/database.mysql.inc on line 66.

i'm wondering if i downloaded and installed 4.5.2 or some other not yet-fully ready version, and that is why i'm having some of the forum, and rss problems...
thanks,
eva

hello,
i saw a bug report with no comments posted on the 19th. what does this mean, has anyone else had this problem and fixed it? when i go to post a forum topic i get the following error:

warning: sprintf(): Too few arguments in /home/..../drupal/includes/database.inc on line 147.

i also get:

user error: Query was empty
query: in /home/....drupal/includes/database.mysql.inc on line 66.

I just followed the installation procedure found in the instructions to go to 4.6.0. When I ran update.php it show the page just fine.

But ... when I clicked on "run the database upgrade program" I get this text only, "unsupported database type"

Any ideas? Everything was working perfect with 4.5.2 before.

Thanks, Tim

The requested URL /node/1 was not found on this server.
