Getting 404 error when i want to buy plan / pack
I'm trying to set plans and packs for test, but each time i click on confirm, after i have slected the plan or pack, i'm getting redirected to 404 page.
Sandbox is disabled, i do'nt want to try in sandbox. All seem well configured and enable as it should, i checked like 20 times. I can't even post free listing if i create a plan to "buy it" for free.
Any idea what's wrong?
