To update the payment module, you must first delete its previous version.
WARNING: Make sure you save the parameters of your module before you uninstall it and save the production key that is no longer visible in the Lyra Back Office.
Moreover, the new version of the module introduces a new setting: Signature algorithm. By default, this field is set to HMAC-SHA-256 and its value must be the same as in the Lyra Collect Back Office (Settings > Shop). If the algorithm is different, the parameter must be changed via the Lyra Back Office.
- Go to the Extensions > Payments menu of the OpenCart Back Office.
- Search for the old version of the installed module and click Uninstall (-).
- Delete manually the lyra.php and lyra_multi.php files located in the following directory: /admin/controller/extension/payment/
- See next chapter to install the module.
