 * This is a imposible to recover deleted variations if you have visited the SKU
   Error Fixer plugin settings page and click on “Delete old variations fully” button.
   
   These variations of variable products when it type have been changed from variable
   to Simple does not remove automatically with changing product type. If you change
   the product type back to Variable, old variations are return. But before that,
   if you visited the SKU Error Fixer plugin settings page and clicked on “Delete
   old variations fully” button, you will not be able to recover deleted variations.
