Upgrading Drupal

Hello,

This is my first site using Drupal. Actually, there are 2 sites in total as a multisite configuration on a local host.

Can I upgrade straight from version 6.17 to 6.19?

Or do I need to upgrade first from 6.17 to 6.18, and then from 6.18 to 6.19?

Thanks

Hello. I am updating an older Drupal website from 4.7 to 5.23. I have followed the steps listed on this below page three different times, and every time I receive the same error for each content type:

user warning: Table 'databaseX.content_type_content_blah doesn't exist query: ALTER TABLE content_type_content_blah CHANGE field_blah_value field_blah_value longtext in /var/www/vhosts/website.com/httpdocs/includes/database.mysql.inc on line 174.

I upgraded drupal from 5.x to 6.17. Everything is ok, except every template I use has empty $sidebar_left and $sidebar_right vars. So every theme (the default themes too) is unusable. I followed the update istructions, disabling modules and themes, and istructions in this post http://drupal.org/node/292167 but with no results. Thruth be told, i had some errors during the upgrade ( http://dl.dropbox.com/u/3112079/drupal_errors.txt ).

I have just done my second upgrade from version 6.17 to 6.19 and lost all css formatting for all themes. The site is there but there is no css formatting for any of the core themes.

I use Drupal as a frontend for MyBB. A MyBB plugin was developed, that would take MyBB users and populate them into Drupal as they are created. There is also a PHP file that can be run, for MyBB users that were in existence before the plugin was in place. The plugin populates the Drupal DB with the MyBB user and password info, and has apparently been tested and working in the past.

I installed the latest versions of MyBB (1.6) and Drupal (6.19) on my site, and was excited to use this plugin, to allow me to take fuller advantage of Drupal's features. The plugin did what it was supposed to do, but the plugin-generated Drupal user's password does not work when trying to log into Drupal. If I reset the Drupal user's password to what it was already supposed to be, there is no problem.

I contacted the plugin developer, and his only explanation is that Drupal's password handling must have changed in the recent past. This plugin was tested and working on a previous (6.x) version of Drupal (and the developer does not have Drupal 6.19), but at this time I do not know which version. I am just trying to figure out if anything has changed in Drupal, anywhere in the 6.x versions, which would cause this MyBB plugin to stop working properly for populating passwords?

The following downloads are provided for those users who do not find it necessary to overwrite all the files within their Drupal 6.x installation when an update becomes available. Using a file comparison utility, the following update zip files contain only the date modified Drupal core distribution files which have been changed, added, or updated since the previous release.

Upload the new files to your Drupal site, then log into your site as the administrator and run update.php. A link to the update.php file can be found on the Administer » Site building » Modules page.

After running update.php, your Available Updates and Status Report functions will indicate that you are running the latest Drupal release version.
