If you see "Error establishing SSL connection: certificate verify failed" in Miva Merchant, there might be an easy fix.
Keeping your Miva Merchant store up to date is the first step in resolving eCommerce SSL errors. Sometimes this means contacting your host or a module developer. Usually Miva Merchant and Miva Empressa updates are painless and quick.
