Tag manager, create new variable, SQL problem

Ok I’ll reply to myself
In this post I found the solution.

So if you have the same issue, please try :

ALTER TABLE `matomo_tagmanager_tag` ADD COLUMN `description` VARCHAR(1000) NOT NULL DEFAULT '' AFTER `name`;
ALTER TABLE `matomo_tagmanager_trigger` ADD COLUMN `description` VARCHAR(1000) NOT NULL DEFAULT '' AFTER `name`;
ALTER TABLE `matomo_tagmanager_variable` ADD COLUMN `description` VARCHAR(1000) NOT NULL DEFAULT '' AFTER `name`;

Regards,

j.
