Upgrading Drupal

The error occured when i did the installation to update Internationlization module to the newest version for drupal 6.x -- version 6.x - 1.6
Here's the warning for errors:

Hi,

We have a small site where our old (D5) content and database is just too crossthreaded to perform a direct upgrade.
So, a piecemeal upgrade is planned and we'd like to
be able to access the old D5 drupal installation as the subdomain d5.mysite.com
while we work on the new site.

Not sure that I'm posting this on the right forum page; if not, I apologize and ask for further advice where to post it.

When trying to change Style option on Views->Block->Basic Settings to "HTML list", I'm getting this message:

* warning: Parameter 3 to views_ui_build_form_state() expected to be a reference, value given in C:\wamp\www\views_school\sites\all\modules\views\includes\admin.inc on line 1606.

Hi,

Over the last year I have familiarised myself with Drupal due to getting more and more requests for websites with CMS.

I have created one site so far and currently working on another aswell as having my own site built on Dupal.

I have got another request for a website with a CMS and possibly a shopping cart.

Hi!

I try upgrade Drupal from 6.x to 6.19 following step by step instructions from UPGRADE.txt file and I just delete theme made by me.
I just delete all old Drupal files and extracted new. Then I copied old .htaccess, robot.txt and sites directory but I just figure out I lose my theme (made by me) :| Please add this step to avoid problem like this for Your users in the future.

I had GoDaddy update my Drupal install from 6.17 to 6.19. After the update I can't logon. I type in my username and password for the admin account and it just takes me back to the same page but doesn't log me in. There are no watchdog messages, if I enter the wrong password it gives me the standard watchdog message. It just seems like the login info isn't taking and it looks like it is just refreshing the page.

Does anybody have any ideas?

Thanks
