Drupal 4.5.x or older

I'm seeing the following error using the update.php script when attempting to upgrade from 4.5.7 to 4.6.5:
warning: Invalid argument supplied for foreach() in /home/webroot/htdocs/update.php on line 98.

The dropdown only shows 'perform updates from' -> 'all' or 'no updates available'.

Any ideas what could be causing this issue?

Drupal Version 4.5.7
Apache 2.0
PHP Version 4.3.11
MySQL Version 3.23.58

Er, so I've been a bit slack with my upgrades.

I've got 3 sites still running on drupal 4.3.2, each installed in a different directory, and I'd like to upgrade them all to 4.6.5, and preferably merge the install directories together using the sites/whatever.com mechanism.

I've tried jumping directly to the latest version, but with no luck.

Any suggestions?

Oh, and should I just jump to 4.7.0-beta2 while I'm at it, anyway?

If anyone could answer this I'd really appreciate it. I've been trying to track the issue for months and still not been able to figure out what is keeping a user from being able to log in to my site from "http://www.domainexample.com".

Right now people can only login and remain logged in by entering "http://domainexample.com". If they put the "www" in there they're not seen as logged in. It's a 'small' problem, but a really annoying one, too...

Pros: imposible to install..You need to know all about mysql,php,cms,programing,coding,ewerything....Useless
program

Cons: Well the thing i dont get with the folks creating cms
systems.....HOW DO THEY MANAGE TO CREATE THE PROGRAM,,,,BUT NOT MANAGE TO EVEN
CREATE/PROVIDE A SENSEBLE INSTALATION PROSEDURE???????????????

Why do people even try to say you dont need any mysql php etc knowledge when
one needs to hire a "company" to install it...Its a freeware i know
but ive been wanting to try cms as foundation for my site but i`ve not been
able to, because of that i havent managed to install even one of the free programms
that are out there...

The day i see a developer that has the knowledge to make a deasent instalation
of what they create...well then il give them 5 pages of ads and fact and yep,,
all they want.

As for now there are not one single good program out there,as this is not good
either...

I think i have the rights to complain about it and think about this:::::if
you were to create a program....?wouldnt you prefer to make it posible for people
to use it....??????????????? i know i would.

Tired of all the *****....

============================================

This is by far one of the most ridiculous reviews of Drupal I've ever seen. I wonder if this person has ever bothered to check out the support pages, the handbook or even the forums for any help. Now, I'm no Drupal or php, mysql, cms, expert, by any means, but the support is there for those that need it. Sometimes it may take a while, others not, but a little bit of searching really helps. Installing Drupal takes what 5-10 minutes? For more complex issues, you may just need to hire someone from the services page to help you, or for basic things just ask in the forums.

I have had a 4.5 drupal site for about a year. I am building a NEW 4.6 site. (Yes, I am starting all the content over...) But I would like to keep my existing users. What is the easiest way to do this?

Thanks!

I am trying to upgrade from 4.3. I tried upgrading to 4.6.5 and now I have tried upgrading to 4.5.7. I have tried multiple times and each time the same thing happens. When I go to www.mysite.com/update.php and (after following the instructions for adding the appropriate tables) click the "run the database update script" nothing happens, it takes me to a blank white page. Then if I try to go to the home page, same thing, a blank white page. No errors, just plain white. Help!?????
