MultiSafepay eZ Publish payment gateway
This README is terrible it gives no info at all I worked out it was a multisafepay extension from the folder name.
Please be aware that Multisafepay require unique transaction IDs we have had issues with Rollbacks where transaction IDs and order numbers have been resent and the module does not fail gracefully when receiving an error from the gateway.
If a rollback is performed you need to bump the Auto-increment ID of ezorder and multisafepay_transactions as it will try and re-use previously used IDs which causes a lot of issues.
