Removing a module/page from the Game CP v2 is easy. Simply delete the file and empty your cache by following these instructions.
Example: How to remove Google Checkout?
- Find /gamecp/includes/user_donations_google.php
- Delete that file
- Go to /gamecp/includes/cache/ find the file fileinfo.cache and delete it
- You are done!
The module should no longer appear in your Game CP v2 menu anymore.
