Hi Max,
thanks for your swift reply and helpful solution – awesome support! I will give it a try. While on the one hand I am totally with you with regards to reduce the elements on the checkout page to a minimum – this totally makes sense!
On the other hand – due to our rather strict internet laws in Germany – it may be crucial to display the footer on every page if the footer is the only place with a link to the imprint.
Probably I will just mirror the link in the header navigation – however, your explanation on the child theme encourages me to get my hands on this, cause there might be other workarounds in the future, which will require to cope with the child theme.
Thanks again!
