Oops! Module Not Found Errors


When placing an order, viewing an invoice, viewing the Admin Area invoice or transaction lists, or otherwise working with invoices or transactions, an Error: Module Not Found error displays:

An Error: Module Not Found Errors

Viewing the list of active payment gateways at Configuration () > System Settings > Payment Gateways will also display an error:

The Payment Solution module could not be loaded, most likely because it has been removed. You should deactivate it now.


This error indicates that you have activated and configured the payment gateway, but a corresponding PHP file is missing from the /modules/gateways/ directory.


To resolve this issue, choose one of the following options:

  • Restore the missing module file to the /modules/gateways/ directory. You may need to upload the file to your server via SFTP or restore from a backup.
  • Deactivate the missing module at Configuration () > System Settings > Payment Gateways and switch customers to a different payment gateway module.
