Upgrading Drupal

Hi everyone,

Could anyone help me to fix this?

I did off-line my site for maintenance and i returned it go to online again. But something wired happened. It sill appears off-line when I go to the main page such as www.expample.com but when I go to the other pages such as www.example.com/content/test it works!. I don't what's happened.

Thank you!

Solved

Cron does not run, this is the error:
'The transcoder is not configured properly'
Help ;-(

Previous version - 6.20

Getting the following error when running update.php:

PDOException: SQLSTATE[42000]: Syntax error or access violation: 1231 Variable 'sql_mode' can't be set to the value of 'TRADITIONAL' in drupal_get_installed_schema_version() (line 151 of /path/to/drupal/includes/install.inc).

I would like to modify my current Drupal installation as follows:- Whenever a user registers in my website, I wish to give him a separate website within the same Drupal installation or a separate installation, under the subdomain of my main website domain. Will it be possible to create multiple sites by the registered users as in Wordpress...

I've succesfully upgraded a 6.20-site to 7.x-rc3, it took a few tries but I managed to get the upgrade running with only minor errors.

I've got loads of images attached to the nodes via imagefield (filefield), but they apparently haven't been upgraded to the new file API, as I cannot see the images neither in view or edit mode. Is this correct, or have I missed something? From the CCK-site it looks like they are working on some kind of content migrate module - is this where the images should be upgraded/migrated?
