I have just update my WordPress page and I can't see it. A lot of plugins are giving errors, so I activate DEBUG. Then I have try to desactivate all plugins in the database. To make this I erase the option_value of active_plugins, but now I can only see a blank page when I enter my website, neither the errors!!

Never modify the database options directly. Instead, to deactivate all of your plugins, FTP to your site and rename the
There are several steps your should take to debug an update:
1 - Deactivate Plugins
You seem to have done this already. Good job.
2 - Activate the Default Theme
Some themes aren't compatible with newer versions of WordPress. Switch your active theme from whatever it is now to TwentyEleven (the default that ships with WordPress 3.2.X). If this fixes the problem, then the problem was your theme.
3 - Ask For Help
For the record, the WordPress Answers StackExchange is not a support forum.
If you need specific help with your site, go to the official support forums and ask. Make sure you detail, step-by-step, exactly what you did, what error messages you saw, and what problems you're facing.
"A lot of plugins are giving errors" doesn't help us at all if we don't know what errors you're seeing. Many times, these errors will tell us what went wrong so we can then help you fix the problem.
LAST - Restore from Backups
You did back things up before you ran the upgrade, right? This is exactly the reason WordPress lists this message on the update screen:
So restore your site back to it's pre-update state by re-installing the older version of WordPress and restoring your database from the backup file.
Adding my 1 cent to @EAMann 's awesome answer... After updating WordPress, if you see a blank site or an error that says 'Site down for maintenance', use FileZilla or whatever FTP program you use, and delete the '.maintenance' file from your WP installation's root folder. You may need to set hidden files visible for doing this.
