Upgrading Drupal

I've just updated my site to 4.7. Everything seems to be working except I can't seem to change a fields value in the node_validation function of my custom modules.

In 4.6 under mymodule_validation I could change a value. If I wrote $node->color = 'red' red would be saved, or if there was an error, 'red' would be in the field when the form refreshes.

It doesn't work in 4.7. I can set errors, but when I change the value it has no effect.

Somebody please help

Thanks,
Sam

I tried to restore an old 4.6.x site from backups.

mysql blah-blah-blah <backup.sql
tar -xjf fs_backup.tar.bz2

All files and tables are at their initial places.

But after this I get this instead of an initial page:

{head} {styles}
{_BLOCK_.header.logo}
{secondary_links}
{primary_links}
{_BLOCK_.header.blocks} {_BLOCK_.footer.blocks}
{_BLOCK_.header.title}
{submitted} {_BLOCK_.node.taxonomy}
{content}
{_BLOCK_.node.links}

Dear friends,

I've done an upgrade:
1. MySQL 4.0->5.0
2. PHP 4.3 -> 5.1
3. Drupal 4.6.8 -> 4.7.3

The problem looks simple: all content in russian is not readable anymore!

This is not really an "upgrade problem", but it is the best fit as far as I can tell.

I moved a site I developed on a site using mysql 4.1 to a server using mysql 4.0. I used the 4.0 compatibility flag as suggested here (and in other places) when exporting.

The site looks fine and navigates fine, however, when I go to log in, I get the following errors:

Warning: Duplicate entry '0' for key 1 query: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (1, 'php', 'Duplicate entry '0' for key 1\nquery: INSERT INTO watchdog (uid, type, message, severity, link, location, referer, hostname, timestamp) VALUES (1, 'user', 'Session opened for <em>Webmaster</em>.', 0, '', 'http://wisdomword.com/user', 'http://wisdomword.com/user', '64.4.106.234', 1157693073) in /home/wisdom/public_html/includes/database.mysql.inc on line 120.', 2, '', 'http://wisdomword.com/user', 'http://wisdomword.com/user', '64.4.106.234', 1157693073) in /home/wisdom/public_html/includes/database.mysql.inc on line 120

My hosting provider updated PHP (from 4 to 5) and MySQL and my site was nearly killed. All national chars became strange signs, the headers of the site disappeared and I get the following error everywere:

Hey All,

Just upgraded my site from 4.6 to 4.7 and everything went pretty smooth. Database converted successfully and when I finally figured out that I needed to move my style sheet and some other old stuff from my bak dir to the new site the rest of it fell into place.

I thought it was smooth sailing from there on out but then I noticed in the settings page of the admin node that there was an error as follows:

Multibyte string input conversion in PHP is active and must be disabled. Check the php.ini mbstring.http_input setting. Please refer to the PHP mbstring documentation for more information.

Not having access to the php.ini I wrote a not to the support group that hosts my site (supremeservers) and they responded promptly by telling me I could create a php.ini in the root of my site and add any options I wanted in there. So I added the following line to php.ini and uploaded the file:

mbstring.http_input = off

After clearning my cache and reloading the page the error message went away and again I thought all was good. But, still thinking I needed to make sure everything was working correctly I went through all the settings under admin and sure enough they all were fine. But then I clicked on the admin node itself - the root node that says 'administer'. Thats when I got the blank page.

Viewing source on the blank page gives me nothing - its empty. The url in the bar looks like its pointing to the right place to me: http://magnusontech.net/?q=admin but all I get is a blank page.
