I bought the Business Finder theme but after install on Google Cloud Platform and fill the license info, the site doesn`t work and I recept the message error “Please enter a valid ThemeForest Purchase Code. You can configure it in Theme Options.”. Anyone knows if I need contact the AIT, responsible by this theme, directly or anyone from Envato solves problems like this.
Make sure that there aren’t any spaces when you paste the purchase code. That can sometimes cause this error.
Otherwise, you will want to contact the author of the theme (AIT). Here’s their support page: https://themeforest.net/item/business-finder-directory-listing-wordpress-theme/5443578/support
