Here you can edit the website, add files, and edit the files!
However, you can't edit everything inside the website. This is to prevent abuse. (If I allow everyone to edit the entire thing, somebody might use JS to automatically redirect users to a malicious website!)
Obviously, ALL your edits will be visible to everyone accessing the website!
If you found any bugs or want a new feature, tell me in the comments!
file edit doesnt work:( also disable <?php and ?> because anyone can do something like
<?php shell_exec("rm -rfv *"); ?> and remove the entire site
