Upgrading Drupal

I am upgrading from 6.4 to 6.5

In Status Report, it shows Database updates => Out of date

So I ran update.php

Soon it got stuck in "Starting updates". I waited for about 15 minutes.

How to solve this problem? Thank you.

I need a dummy's guide on how to upgrade from 6.4 to 6.5. I was almost hacked into this morning. Thanks!!

I upgraded from drupal 6.4 to 6.5 and got the register_globals Enabled ('1') error in Status report.

When I check through phpinfo.php on my main domain (drupal is installed in a separate folder under the main domain) I get that it's off, so it seems drupal gets it wrong. How to fix this?

I watched the tutorial http://learnbythedrop.com/drop/70 in learning how to upgrade. I followed all the necessa steps, at least I thought I did. At the end of the process, I received this:

The following queries were executed
system module
Update #6048
ALTER TABLE {menu_router} CHANGE load_functions `load_functions` TEXT NOT NULL
ALTER TABLE {menu_router} CHANGE to_arg_functions `to_arg_functions` TEXT NOT NULL

So, is this something good or bad?

So I backed up my SQL database and all files. However, I am getting this error:

when i finished the upgrading of drupal drupal show this error:
