Vantage theme (appthemes_display_checkout) function code?
I am using vantage theme for my website, but when some one subscribe any of the package after selecting the categories.
Subscriber can edit those categories. He can switch to some other categories. I want to charge them for this, if they change the categories. Please advise how it can be done.
I see all the theme files are calling this function appthemes_display_checkout, but i could not find the code for this function.
