This is so great. And I have this issue whereby after registering a new member and then do the renewal, the issue comes when I tried to view the card from the manage members, when clicked it leads to a page that is not available instead of the page in the code. How do I resolve this please?
Fatal error: Uncaught Error: Call to undefined function generateUniqueFileName() in C:\xampp\htdocs\MembershipM-PHP\edit_member.php:43 Stack trace: #0 {main} thrown in C:\xampp\htdocs\MembershipM-PHP\edit_member.php on line 43
