How do u get a shell? I have a php shell but it gives me 403 error. even when i tested with a file that was not present like ex.php, instead of giving a not found, it gave me 403. How do i change the server to accept php file? Or any other ways?
Try to look and check the code of modules you already see in the admin section. Make your own based on them. Change step by step then if you have to.
