    Tech FAQ

    • Problem: I get a 404 error when I try to configure the plugin
      • Cause: Routing tables not loaded
      • Solution: Open the file global.asax in the root of your webshop. Add a 'white space' character at the end of the file, outside the XML tag. Save the file and call up your webshop. 
    • Problem: The order status is not changed after a payment has been done
      • Cause: You most likely have entered a webhook url in your Mollie Dashboard.This is not neccessary as the plugin passes a proper webhook to Mollie upon payment.
      • Solution: Remove the webhook url in the Mollie Dashboard. Click here to go to your Mollie Dashboard.

    Otherwise, buy support from actOpus.
