Upgrading Drupal

I had some problems after upgrading. But have solved most of them. There is hovever a "small" issue left..

Almost all my nodes turn up blank as in "just a plain white page" when I access dem directly or via link. When i press the "send to a friend" button at the taxonomy-menu page (here) the whole node shows at the bottom.
I have checked my access controll and that shold be i order.
Any idea what I am missing here?

Hi

I have taken over a drupal site that I believe is running 4.7.0RC4. If I update the code to 4.7.4 and try to run update.php there seems to be no database updates, is this because of that it is running a RC or something else?

In changelog.txt I find "Drupal x.x.x, xxxx-xx-xx (development version)" at the top.

Have tried to make a new installation of 4.7.4 and exporting just the data from the old database, but then I get "duplicate of auto increment id" (or similar) when I try to import into the new database.

So my question is, how can I save this site/data?

Or maybe something else; this is my first upgrade, so bear with me . . .

After running update.php, I got 2 errors:

• user warning: Incorrect table definition: There can only be one auto column and it must be defined as a key query: ALTER TABLE node DROP PRIMARY KEY in /***/includes/database.mysq.inc on line 121.
• user warning: Multiple primary key defined query: ALTER TABLE node ADD PRIMARY KEY (nid, vid) in /***/includes/database.mysq.inc on line 121.

Both of these seemed to be under:

Update #180

• Failed: ALTER TABLE {node} DROP PRIMARY KEY
• Failed: ALTER TABLE {node} ADD PRIMARY KEY (nid, vid)
• ALTER TABLE {node} ADD UNIQUE (vid)
• ALTER TABLE {node} ADD INDEX (nid)
• ALTER TABLE {node_counter} CHANGE nid nid INT(10) NOT NULL DEFAULT '0'

I'm doing this on a test site, which I hope to just move my dns to (the site is fairly static). There is a vid field in the node table (that isn't in the old site), and it has the same values as the nid, but it is not set to auto_increment (other structure info seems the same in phpMyAdmin).

Everything seems to be working reasonably well, however. I have most of the added modules back in, and the site is functioning well--I just want to make sure something awfult won't rear its head down the road. Thanks!

I posted a question yesterday (here..) And after some cursing and tweeking I finaly have some progress. It is now possible to see some of my page ( www.panurgus.no ) but heading and blocks are missing, and I can not access all of my categories.

Is this a "theme" problem or something else?
If so: Where can I change theme when I'm unable to reach admin-pages?

Recently I tried upgrading the www.paramedicduquebec.org website. I failed. I use some external module like i18n and fckeditor. I need them all to work. I need all my data not be lost. I want my site exactly like it is now but under 4.7.0 official distribution. I will do the security upgrades. If there is anyone interested please contact me in this thread and give me tour email address. I am ready to pay.

Thank you

Just upgraded from 4.7.3 to 4.7.4 and got a whole raft of errors.

I think I tracked down the only real problems, related to the contacts module. It looks very much like drupal and this module are using the same table name. Perhaps all module tables should have a prefix in the future to differentiate them from core?

If anyone has time, please take a look at my errors and let me know if any of them are something I really need to worry about. I did go manually drop and recreate the contact table.
