Upgrading Drupal

Hello,

Drupal 5.3, PHP 4.4

I am 2 months new to Drupal and have 'always' had this problem when running the upgrade script.

Updating

An unrecoverable error has occured. You can find the error message below. It is advised to copy it to the clipboard for reference. Please continue to the update summary

An HTTP error 404 occured. update.php?op=do_update

The update summary yields:

Drupal database update

warning: reset() [function.reset]: Passed variable is not an array or object in /home/foo/public_html/update.php on line 523.

The update process was aborted prematurely while running update # in .module. All other errors have been logged. You may need to check the watchdog database table manually.

When I try to move my Drupal installation (which was new with Drupal 6 Beta 2) from Beta 3 to Beta 4, the update.php doesn't do anything. When I run the file, I get a blank page.

I have a 5.0 site which is quite buggy and I will want to upgrade to 5.4 . If I upload fresh (5.4) files in replacement (minus configuration files) what is likely to happen ? Will my site crash ?

I did everything I was suppose to for upgrade, when i go to the url site/upgrade it directs to install page, did i miss something ?

Hi there,

I upgraded to 5.4 today, and have some problems with my views now:

For all exposed filters the first taxonomy term isn't listed. Does anyone else have these problems too?

Thanks,

If my site is on version 5.1, can I just straight to 5.4, or do I need to do each previous upgrade one at a time?
