Hi and thanks for for your response.
No it was not an older version of DGWork before but a complete different theme. Everything worked regarding easy digital downloads as expected. We installed and configured DWWorks – the child theme which was part of that bundle is active – and now the two mentioned issues appear.
What exactly do you mean by “Do two sites install the same plugins?” ?
It’s a single wordpress instance. Easy digital downloads was already installed before we installed the DGWork theme.
referring to your request to check the affected site, it’s not that easy. We have to do that via private message or similar.
