Upgrading Drupal

Hi,

I just tried upgrading a 6.20 install to 7.0 but encountered this on running the update script.

PDOException: SQLSTATE[42S02]: Base table or view not found: 1146 Table 'MYDBNAME.blocked_ips' doesn't exist: SELECT 1 FROM {blocked_ips} WHERE ip = :ip; Array ( [:ip] => 123.123.123.123 ) in drupal_is_denied() (line 1779 of /PATH/PATH/PATH/PATH/html/drupal/includes/bootstrap.inc).

Please give advice.

Thanks.

I get the following message.

Notice: unserialize() [function.unserialize]: Error at offset 120 of 120 bytes in variable_initialize() (line 749 of /home/content/s/h/e/shelton2/html/includes/bootstrap.inc).

I am new to Drupal. I tried the Drupal 7 rc2. Today Drupal 7 is released . How can I upgrade from the Drupal 7rc2 to Drupal 7 just release today Jan 5, 2011. What do I need to do? Can someone tell me how?

I've tried to upgrade D7 site from 7.0 alfa6 version to the 7.0 official release (wrong step? should I do a new clean installation instead?) and I am getting the error:

An unrecoverable error has occurred. You can find the error message below. It is advised to copy it to the clipboard for reference.

Hello there,

Upgrading to Drupal 7 has turned in a bit of a nightmare. I solved a few problems thanks to older forum threads but the problems seem endless, as I go. I followed the instructions though. the only thing I forgot to do, was to put the website back to English, so it was set in French before upgrading.

My issues:
/admin/build/ instead of admin/structure in Drupal 7 This is an old issue, though, but current for me. I solved this by disabling duplicate menus (old ones from D6).

I have two fields displayed in a Drupal 6 content type using the Link module. field_newssource and field_download. After upgrading from Drupal 6 to Drupal 7, my content types and all nodes(articles/posts) within are converted to work with Drupal 7. Unfortunately, when I view the articles/posts, those two fields are no longer displaying their content after the upgrade! I've tried installing the Drupal 7 Link module and setting up my content types with the same field, but the original data is no longer available.
