We found the conflict and are now making changes at our end to make it work.
It was not the Redux plugin.
Thanks for your time.
Best,

Thanks for your reply. We use a custom-made theme, so I suppose there could be a conflict somewhere. Replacing the theme with another one for the same reason is not easily done. Is there a way we can set up some error logging to see what happens, when we network activate Redux?
