Upgrading Drupal

I've upgraded an old 4.x installation to 5.x and then to 6.6 and I have some problems:
- some pages informations are no more accessible to administrators when they modify a page, like revision informations, input format, workflow, comments settings, author informations, and so on.
- the same settings are not editable on data types settings in site structure administration.

- some old links like chatbox are present in admin block, but I've no more chatbox module and I want to delete them. where can I find it?

Thanks in advance!

I moved my database and website to a new host. I got everything working but decided it was time to upgrade to 6.x before changing my nameservers and moving the domain to the new hosting.

I've upgraded before and know how to do it. This time however, after moving all the new files in and going to upgrade.php, once I click the continue button (after a warning about register_globals), I just get a 500 Internal Server error.

Any idea what could be happening?

We are in the process of upgrading the og_forum module with other drupal modules we are using and upgrading.

Presently we have og_forum module v 1.11.2.11.2.11 2007/10/26
and we had to do a small change in the og_forum module, because of the following:

Reason: "Forum Posts by members of a group don't appear in the forum container/list"

I have drupal 6.5 and i have to update to drupal 6.6 it's critical to my theme it says how would I upload this onto my server? I have a network location set up but i don't know how to access this one particular site.

We do our site updates on a development server so we can test everything and we are seeing something wird. The process goes like this.

> Pull production site backup to development server & install fresh
> Perform updates to drupal core and / or modules
> backup full site & database from developmet
> Take production server offline, delete data from database & all files
> Install database & files from development
> Bring server back online

Hello All,

I have a site that was created by another company using Drupal and the site is greate. My company has taxed me with create a duplicate of this site for development, and eventually production work. I have tried duplicating the website twice with a better effect the first time than the last one.

The first time I created a duplicate of the site right on the production server, changed the settings.php file to point to the new DB, and did a DB dump and import of the old database to the new one. The home page comes up in all it's glory, but all the links bring me back to the original site. Even if I try to manually type in a page (eg. www.example.com/publicB-html/subpage) I get a page cannot be displayed but the original site works (eg www.example.com/subpage). The admin page on the seconds site also does not work. Looked around and came across this link on this site: http://groups.drupal.org/node/11559. I am currently waiting for my hosting company to get back to me on that so I can give that a try.
