Hello yuberlin,
It seems that you already had an issue before 3.7.2.
You can try to run the following query (after changing the prefix):
ALTER TABLE `#__cck_core_fields` ADD `storage_cck` VARCHAR(50) NOT NULL AFTER `storage`;
It can be found in pkg_seblod_3.15.0.zip/extensions/com_cck.zip/admin/install/upgrades/3.6.5.sql
I would suggest to check the various queries from 3.6.5.sql to 3.7.2.sql and compare or run them manually via PhpMyAdmin.
Then you, you should try to update to SEBLOD 3.8.0 first.
Regards,
Saba
