Help a Dumb Ass With His Tinyboard Problems

So I made my tinyboard chan. I'm not a programmer though and I'm really confused on this php stuff.

Whenever I make a change in the instance-config file, it shows up for me when I view it locally(like when it says .html at the end of the url), but not for people viewing it from other machines.

Also, I restarted my computer and I can't go anywhere on the site except for the home page. I tried to go to (chansite).org/mod.php, but I got a 403 forbidden error.

I have no idea what's going and I'm scared.

i have been hacking seince i was 7 (im 13 now) my parents supported it, and it has helped many people, i have helped add security to sites by testing security, and there is a whole group of hackers im a part of at hackthissite.org hackers arnt bad, those are "crakers" who are mindless morons, you sir are the idiot, you trust the media, you didnt research you are the bad one. i have hacked many things but, for good. are you saying a site about killing people becuse of there race and supports it should stay up?? is that better than hacking?? i have hacked a site like that and shut it down. think im bad? F*ck you!! i have broken some laws but, for good reasons, the government makes you think hacking is bad because the govrnment fears us, but us hackers dont fear them, so the government uses people whot think there hackers and shows them on tv then, people think thats what a hacker is. hacker acually means "one who is experienced in computers and problem solving" i think i have done good, and that i dont hack like black hats who are morons (pretty much "crackers") i hope i will change your opinion.
