CORRECT VIRTUAL STORE ERRORS

The project consists of correcting errors in our virtual store www.buencalzar.cl at the Back office level. In this store, the migration to Prestashop 1.7.8 was carried out and it was left with errors regarding the change of order statuses, automatic email templates were reset and the originals must be restored (it has backup) in addition , the store presents errors in the modification of the products since it does not save the changes.
We will make a detailed list of errors.
