Upgrading Drupal

Hi, I am not sure if I upgraded my site correctly. I was running drupal 4.6.0. I backed up all my databases and files. Then I downloaded the 4.6.2 package, unzipped it on my hard drive, and uploaded all of these files over the 4.6.0 files. I changed the settings.php file, uploaded it, then ran the update.php file. There were no errors, so I assume it worked. However, when I go to the main directory of my site, I get the following error:

Fatal error: Call to undefined function: drupal_add_link() in /home/letscon/public_html/drupal-4.6.0/modules/node.module on line 1609

I am utilizing the basic mail module. After sending out several emails, I noticed that the closing of each email grabs the author name and date. The author name gets linked to the author's profile.

I'd like to remove that link to the author profile, as well as modify the closing because right now it spits out unreadable characters. I've looked through the code but to no avail.

I'm using the mail module found here:

http://drupal.org/node/10227

Thanks in advance for your help.

Hello All,

Our development team is implementing a site based on DRUPAL (http://www.publicvoting.org) and because of some designer requirements we have to change parts in the forum, taxonomy, node, filestore2, etc... modules.

However, if we want to migrate to a newer version of the DRUPAL the changes could be easily lost. I was thinking of overriding the changed functions but it does not seem to work - PHP refuses to override functions...

What would be the best approach to make the extensions?

Hello,

I've just stared using drupal for a project I'm working on, its the first CMS that I've used that does eveything I need. However I'm unclear on a few things, I've been trying to install the 'bookmark' module but I have no idea about creating sql tables, my knowledge of php and sql is very limited.

Any tips?

Thanks

I have upgraded gallery from beta 3 to beta 4.
After the upgrade process I had few problems with my gallery when embeded into drupal

1) The side bar, appears with the gallery content
2) The gallery block, does not appear with the expected menu items

Looking at the code and the output I get from galley I can see that the information expected by
the drupal gallery module is not returened by gallery.

I have found few workarounds to make my gallery work but this should be changed in the gallery.module

I am moving my current site from my current server to a new one. It seems like the perfect time to upgrade my 4.5 version of drupal to the 4.6 which all my other sites are running.

I am going to export then import the database and copy the other files across. Then comes the time to upgrade. My major concern is that I have installed allot of modues as the site was first used for testing then turned into a production site. I know not the best thing to do and now I regret it. My database has allot of waste in there. Any sugestions of the best way to remove all the waste?
