Upgrading Drupal

Hi there,
I'm having a few problems after upgrading. The upgrade went ok but now when visit the testing site, I hit the home link and I get "Page not found". My url becomes XXXXX/?q=?q= and after that all links lead to same thing ?q=?q=archives etc...(except if I click a forum topic) If I remove one ?q= the homepage (and others) appears correctly!
Another problem is when I logout (admin and user), the navigation menu under the login is still on with permission to continue (without the logout and my account options).
Can anyone help me?

thx in advance,

Hi,

I have cpanel and fantastico through my hosters and I got Drupal installed using it. Currently it's telling me I should upgrade to 4.5.1.

Now I had a site failure just before Christmas that turned out to be down to a fault with my hosters when upgrading/altering PHP. However, it scared me enough that I clicked the upgrade option.

The result seemed to be that I lost ALL my data...However there was a backup so I asked Affordable Host to roll it back for me, which they did.

I just upgraded to 4.5.2 and I'm having a ton of problems. Most of them I'm just going to work on figuring out myself, but one of the problems is really hurting my site.

If a user is logged into the site, and then clicks on a node headline - that person is automatically logged out. They are also logged out when submitting a node - be it a story, comment or forum topic.

This is making it almost impossible for users to post comments, and making it very difficult for anyone to post story or forum topics. Of course it is keeping comment spam down - hee hee.

I upgraded to 4.5.2 and installed the updated title.module, but in my old site where the [ title ] links worked, now all I get is the raw text with the square brackets. Even if I edit or create a new page the square brackets around words still do not give me a link.

It used to be that to get the Title module enabled one also had to go to Administration » site configuration » filters. Now there is no such path and title doesn't show up under /admin/user/configure/permission.
I get no errors in the Apache error_log and all permissions seem to be ok.

I am trying to upgrade from 4.4.1 to 4.5.2. Among the many problems I am having, I can't seem to figure out this error which is returned at all times:

user error: Unknown column 'name' in 'order clause'
query: SELECT * FROM menu ORDER BY weight, name in ./includes/database.mysql.inc on line 125.

I just upgraded to 4.5.2 and after running update.php I now get the following error:

warning: Illegal offset type in /modules/taxonomy.module on line 596

I'm running mySQL if that matters at all.

I don't know enough about PHP to figure it out, but it appears to get stuck in the taxonomy_get_tree function declaration, at if ($children[$vid][$parent]) {

Any ideas? I't hasn't killed the entire site, but any page that needs to get a taxonomy list is failing. So while I can read a story, I can't browse a story.
