 * Hello,
    I strictly followed your procedure for Jigoshop migration but I keep 
   getting the same critical error and message when I try to migrate something (
   must be in array… TaxServicE.php…)
 * Here are all error messages, from after activating Jigoshop Ecommerce to the 
   collapsing of the website due to a migration try:
    es WordPress : [Duplicate 
   column name ‘tax_classes’] ALTER TABLE `wpstg1_jigoshop_order_item` ADD `tax_classes`
   VARCHAR(170) NOT NULL AFTER `title`;
 * L’extension a généré 597 caractères d’affichage inattendu lors de l’activation.
   Si vous voyez un message « headers already sent » (Les en-têtes ont déjà été 
   envoyés), des problèmes avec les flux de syndication ou d’autres erreurs, essayez
   de désactiver ou enlever cette extension.
 * A communication error has occured, please reload the page and continue with the
   migration.
 * Catchable fatal error: Argument 2 passed to Jigoshop\Service\TaxService::__construct()
   must be of the type array, null given, called in /home/minimots/www/staging-3/
   wp-content/plugins/jigoshop-ecommerce/src/Jigoshop/Factory/TaxService.php on 
   line 34 and defined in /home/minimots/www/staging-3/wp-content/plugins/jigoshop-
   ecommerce/src/Jigoshop/Service/TaxService.php on line 31
 * Please help me as I urgently need this migration to work.
    Thank you in advance,
   Regards,

 * Hi
    Did you have any tax classes prior to the migration? This error implies that
   you haven’t – if this is not the case, then your tax classes haven’t been properly
   migrated.
 * Since this issue can have many probable causes, it’s best to contact me directly
   at [support@jigoshop.com](https://wordpress.org/support/topic/urgent-migration-issue/support@jigoshop.com?output_format=md)–
   there I might be able to debug the issue properly, since here my options are 
   severely limited.
