Upgrading Drupal

Hi there,

I just upgraded my site from 7.12 to 7.14 and when running update.php I receive a huge long list of php warnings and notices for the list and taxonomy modules:

Warning: Missing argument 2 for taxonomy_options_list() in taxonomy_options_list() (Zeile 1375 von /home/www-data/xxxxxxxx.com/modules/taxonomy/taxonomy.module).

Just updgrade my Drupal from 7.12 to 7.14, in all pages gives me always 404 Not found. what i did wrong in the upgrade? how can i fix this error? Already tried to change the menu.inc to this

//if (variable_get('menu_rebuild_needed', FALSE)) {
menu_rebuild();
//} and dont work, the drupal is running on Internet Information Services 7.5

Just follow this tutorial http://www.youtube.com/watch?v=sBKDzLbG6RE

I was able to successfully upgrade the core, but I am having trouble when I move on to CCK. I go to admin/structure/content_migrate, I select the fields which I would like to migrate (a TEXT and a LINK field), I press "Migrate selected fields" and I am met with a basic Drupal page whic simply has two headers that reads:

You are here
Migrating data

My site is at another place, which I could access using ftp tools.
One day I updated it from drupal 6.x to drupal 7.x, without setting theme to default.
Now my site is drupal 7.x, and it seems the theme I've been using since 6.x can't work well. Basically nothing shows up when the theme is on. I can't find any button I could click. I think something might be wrong so I deleted the theme under sites/default/theme/. Then I can see some buttons on a white page. Still I can't find any button regarding modules or themes.

I upgraded to drupal 7 and everything is working correctly except when I try to list any menu links, then I get a WSOD. I have rebuilt all of the admin menus by deleting them from menu links table and cleared the menu cache. There are no errors popping up in the logs and have put more memory into the php.ini file to see if it was a memory issue. Still the issue keeps popping up. I have looked in the forum for the days and can't seem to find anything about it, does anyone have any suggestions?

I have content types that are left over from drupal 5 newsflash I upgraded to 6 then 7 and now I can't seem to get rid of them. They show up in my cck content types but do not have a delete link next to them. How do I remove the content types?
