That's what I tried, but it's not working right...

Making the site accessible

I renamed the folder cck (under plugin/system ) in cck_out.

Then I create a folder OUT under administrator/modules and moved mod_cck_menu and mod_cck_quickicon in the folder OUT.

Now I could access to the administrator. I went in "Extension manager" and selected "managed" from the left column. I searched for SEBLOD, selected the lines and clicked "Disable".

Now the site worked just fine except for the pages created by seblod naturally.

Updating SEBLOD

I downloaded and installed the last version of SEBLOD

I recieved the following error:  1060 Duplicate column name 'asset_id' SQL=ALTER TABLE `jsm_cck_core_types` ADD `asset_id` INT( 10 ) UNSIGNED NOT NULL DEFAULT '0' AFTER `id`;
and couldn't access to the site again.

Following two other errors I tryied to create the table was missing so I went in phpmysql and created the following table: joo_cck_core_objects width the following four columns:
name options component view
and I populated with the following two lines:
1. seblod3 - <empty> - com_cpanel - <empty>
2. seblod3 - <empty> - com_installer - <empty>

Then I went into the "Extension managare - Update", selected SEBLOD 3 and updated.

I erased the "cck_out" and the folder OUT I created at the beginning.

Now the site is up and the extension work partially. My SEBLOD2 application don't work.

For instane, an error I get accessing the App Folder:
Unknown column 'a.home' in 'field list' SQL=SELECT a.id as id,a.title as title,a.name as name,a.color as color,a.introchar as introchar,a.colorchar as colorchar,a.depth as depth,a.lft as lft,a.rgt as rgt,a.featured as featured,a.home as home,a.published as published,a.checked_out as checked_out,a.checked_out_time as checked_out_time,u.name AS editor FROM `jsm_cck_core_folders` AS a CROSS JOIN jsm_cck_core_folders AS parent LEFT JOIN jsm_users AS u ON u.id = a.checked_out WHERE a.lft BETWEEN parent.lft AND parent.rgt GROUP BY a.id

Don't know if help. Any idea?

Thanks,
Marc
