Upgrading Drupal

Er... how do I activate a module, or stick it onto my sample Drupal site?

I have downloaded the module. I have installed Drupal, using XAMPP. So now I should be able to go round inside the Drupal menu and "switch on" or "attach" the module somehow, right?

apologies...

Have a 5.7 install. I following the upgrade.txt. I made backups and disabled all modules.

I've removed all but my modules, sites, and files directories and copied in the 5.9 stuff.
I run update.php and it says 'no updates available' (not sure if it should say something else in the dropdown) but I run update it quickly goes to 100%.

But when I look at status report it tells me 5.7.

I'm currently in the throws of upgrading a complicated site (which happens to be my personal blog) to Drupal 6 from Drupal 5. Way back in 2004, I stumbled upon an issue which claimed it was possible to allow multiple parents for a node in a book outline, but that an interface hadn't been built for it. That doesn't prevent people like me from adding an entry in the {book} table, my example being a video of a SkyTrain (Vancouver's elevated rapid transit system) appearing in the "SkyTrain" book outline as well as the "Video" outline. It worked like a charm!

In my first test upgrade (intended to document issues of a real upgrade while keeping the existing Drupal 5 site alive), though, I found that my entire book outline completely disappeared after running update.php. After looking at the related error, I think I know why, and have a "solution", which is to hack book.install.

* user warning: Duplicate entry '6019' for key 1 query: INSERT INTO book_temp (nid, parent, weight) SELECT b.nid, b.parent, b.weight FROM book b INNER JOIN node n on b.vid = n.vid in /var/www/staging/DRUPAL-6/html/modules/book/book.install on line 127.

I have had this problem since upgrading to 5.9

Fatal error: Call to undefined function _widget() in /home/musicoll/public_html/sites/all/modules/bio/bio.module on line 124

Visitors are unable to register! I have to disable the bio module!

Hey all. I just upgraded a site from 5.7 to 5.9. I followed the update.txt very closely. Now a couple of my views get Mysql errors. I'm hoping that these may make some sense to some of you so you can point me in the right direction. Thanks!

I am just fiddling with the upgrade process and moving a vbDrupal to Drupal 6.3. Unfortunately the 6.3 upgrade stops with the following error shown on the page.

An error occurred. http://biohints.com/update.php?id=6&op=do <br /> <b>Fatal error</b>: Call to undefined function node_get_types() in <b>/path/modules/comment/comment.install</b> on line <b>50</b><br />
