Upgrading Drupal

I have been toying with installing some modules, removing those that didn't fit the bill. Somewhere along the way, I've lost a couple of columns in the admin area.

Specifically, weight is missing from the blocks area. The column is present but blank. In ePublish, the topic is missing. Same deal.

If I look at source code, I get something like this:

<select name="edit[user][1][weight]" id="edit-user][1][weight">

or

<select name="edit[tid][114]" id="edit-tid][114">

My hosting company (where I have several Drupal sites) have just advised me that next week they are going to upgrade Mysql (from 4.0.26 to 4.1.15) and Php (to 4.4.1).
Can anyone point me to any problems these upgrades may cause me with Drupal 4.6.3?
I would love to find out ahead of time so I can prepare.

Thanks in advance for your help,

Okay, so upgraded from 4.6.3 to 4.6.4 by uploading the following files from 4.6.4 to my installation (thus replacing the old corresponding files):

includes/bootstrap.inc
includes/common.inc
includes/database.mysql.inc
includes/database.pgsql.inc
modules/aggregator.module
modules/blogapi.module
modules/filter.module
modules/system.module

includes/file.inc
modules/upload.module

modules/user.module

I was able to do this because I just took note of the files to be patched in the patch files found in the upgrade instructions of 4.6.4 -- http://drupal.org/drupal-4.6.4.

That is:

To patch Drupal 4.6.3 to Drupal 4.6.4, use the patches below:
http://drupal.org/files/sa-2005-007/4.6.3.patch
http://drupal.org/files/sa-2005-008/4.6.3.patch
http://drupal.org/files/sa-2005-009/4.6.3.patch

However, there are no equivalent patches in the instructions of 4.6.5. -- http://drupal.org/drupal-4.6.5. Only these less precise instructions:

Bugs fixed

The most important bug fixes since Drupal 4.6.4 include:
Patch #29133, #39566, #39670: fixed problem with URL filtering that caused table sorting and pagination to be broken.
Patch #22200: fixed problem with aggregator that resulted in content being filtering twice.
Patch #38889: fixed problem with using multiple database connections.

A complete list of all bug fixes in the stable DRUPAL-4-6 branch can be found at http://drupal.org/cvs/drupal/?branch=DRUPAL-4-6.

If I use the Collimator module with Drupal 4.7-beta1, I receive "No Data" as result instead of a list of nodes.

Has anyone already got a working version of Collimator for 4.7? Thanks!

Upgrading from 4.64 to 4.6.5 cause the following error.

I get the following error and cannot access my site after the 4.6.4 to 4.6.5 update:

Warning: mysql_connect(): Access denied for user: 'username@localhost' (Using password: YES) in /home/xlecom/public_html/includes/database.mysql.inc on line 31
Access denied for user: 'username@localhost' (Using password: YES)

Can anyone help to correct this error?

I think this just started showing up with an upgrade to 4.6.4. My log file seems to be getting full of errors: "Page not found" errors are generated by images not being found. Almost the images are specified in the style.css files, are actually visible (therefore definitely found), and are being looked for in the root directory of the installation rather than in the theme directory.

I'm thinking it might have to do with a search cron job but the times don't match. Or with clean_urls (which I've just turned on just before the errors started appearing).
