Fatal error: Class PHPMaker2020\project_name\Attributes contains 3 abstract methods and must therefore be declared abstract or implement the remaining methods (ArrayAccess::offer_link, ArrayAccess::project_id, ArrayAccess::country_id) in C:\xampp\htdocs\project_name\phpfn.php on line 2207.

Make sure you have already re-generated ALL the script files, and try again.
