Could you check out why your theme conflicts with plugin “woo commerce multi currency”?
On frontend the rates show correct, but the currency icon does not change and shows only €.
I contacted Villatheme for it, but they referred to you.
If I make a child theme now from the original Gecko theme customized by me, will all customized code be in it?
So if I make a child now, will that child be good to go live and let the original theme auto update in the background?
