Probably because you didn’t mention what you did change on theme.
No. this is a general forum. You should use the comment tab from template page.
you can pay an item without deposit, but the price will go up with few dollars.
I really like one layout from template. Maybe is better to change the default home page to another one. The “wall home page” look way better then default one, and the first impression count. You need to work a bit and on paddings and typography, in special at headings and submenu.
