During Store Commander's installation process, you obtain the error;
The controller adminstorecommander is missing or invalid.
The installation can be finalized because Store Commander cannot be added to Prestashop Modules menu.
An error occured during the creation of object tab (Unknown column 'hide_host_mode' in 'field list')"
You need to fix this by running the following query in your database (adapt prefix "ps_" in table "ps_tab" if necessary):
ALTER TABLE `ps_tab` ADD `hide_host_mode` tinyint(1) NOT NULL DEFAULT '0' AFTER `active`;
Contact your web agency if you need assistance with applying this modification within your database.
