I installed the <b>xrowecommerce</b> on my eZ Publish 4.0.1. I actived the extensions <b>ezoption2</b>, <b>ezurlaliasmigration</b> and <b>xrowecommerce</b>. When I try to work with the webshop, many errors appeared. I suspect that I missed some settings or didn't know how to use it. Could you help me?
