Upgrading Drupal

Hello. I updated my drupal software to the latest version the other day and since then I am unable to access a directory directly through my browser anymore. Now I get a "Page Not Found" page instead of the directly. For instance http://www.nickmoyer.net/act/ should take me to a folder full of files that I was able to access before but not any longer.

What do I need to do to be able to see those files again via the browser.

Thank you,
Nick

Hi guys,

recently attempted essential security updates reccomended in site updates, from version 6.18 to 6.19. Also reccomended to do update.php on following modules:

CCK 6.x-2.8
privatemsg 6.x-1.3
contemplate 6.x-1.2
date 6.x-2.6
filefield 6.x-3.7
imagefield 6.x-3.7

I did the update from 6.18 to 6.19 using softaculous within cpanel on my hosting account then uploded the module updates. Then put the site into maintainance mode and ran update.php.

The update failed on the privatemsg module and I got the following message.

The following queries were executed
date_api module
Update #6006

* No queries

privatemsg module
Update #6007

* ALTER TABLE {pm_index} DROP INDEX mid
* ALTER TABLE {pm_index} DROP INDEX thread_id
* ALTER TABLE {pm_index} DROP INDEX uid
* ALTER TABLE {pm_message} DROP INDEX author
* ALTER TABLE {pm_message} DROP INDEX subject
* ALTER TABLE {pm_message} DROP INDEX timestamp
* ALTER TABLE {pm_index} ADD INDEX list (uid, deleted, is_new)
* ALTER TABLE {pm_index} ADD INDEX messages (mid, uid)
* ALTER TABLE {pm_index} ADD INDEX participants (thread_id, uid, deleted)

I want help upgrading! i tried it before and couldn't figure it out. it anyone could upgrade my site for me that would be awesome!!! Thanks!

Goal: Upgrade from 6.17 to 6.19 and migrate to another web-host during this process
I had experience doing this minor upgrade on another site, so I feel very comfortable that I handled the upgrade process correctly. I think it is the migration that is giving me problems.

I tried to upgrade from 6.15 to 6.19. Before I realised things weren't working well, I was also trying to upgrade pathauto module and install the webform module.

When I tried to run update.php or when activating or deactivating a module I got white screens, but the admin pages seemed ok when I went back to them.

Can some one help me resolving following error, I have installed drupal through fantastico, it was runing fine I don't when this problem initiated.
I have already changed the utf8-unicode to utf-genral through script and after running the script I also convert the remaining ones manually.

I am also getting this time of error when I am enabeling triger module, so I have simply disabled that.
