I'm using custom magento theme, and changed a few things on it. I also wrote this problem to where I bought it.
I've been researched everything about that but nothing helped me.
When I use custom template's /layout/checkout.xml file It’s not progress to “payment information” tab, and also right sidebar checkout progress not working
If I change checkout.xml file from base theme’s checkout.xml file payment information can work very well but checkout progress still not working.
I'm trying to fix checkout progress problem.
Do you know any solution, anynone has same problem or just me?
