I installed Ja Nuevo on my localhost using Xampp 8.1.6, installation went smoothly and I can access the administrator panel. The website itself however displays error:
call_user_func(): Argument #1 ($callback) must be a valid callback, function "imagecreatefrompng" not found or invalid function name
Any suggestion what might cause this issue and how to fix it? I did try to re-install using a different php version without any luck.
