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.

Good think you aren't trying to use Wakaba, because this would be a cock-load harder!

There is a very specific method to make an imageboard. On the first full moon after the solstice, you must cover yourself in bear urine in a grave yard and sing the praises of the Japanese Patron Saint of Eastern-style BBSes, Oiuakamishirosuramaso-sama, who may or may not be there. If this doesn't work the first time, then your nihonjin blood is weak and you have to get his attention. You do this by sacrificing forty niggers to him seventy seven hours before a complete solar eclipse over Jerusalem occurs. Kill them by crucifying them upside down and burning them. Squeeze whatever fluids remain into a jar, then wait three days and ejaculate into the jar. Repeat the graveyard ritual while drinking this fluid with a form of hard liquor of your choice. Now that you've got it set up, please note how extremely important this next part is. You must refresh your imageboard every five minutes for exactly one week. You should now samefag it enough that you manage to get linked to a few times, so that people know about it. After that, you must lose interest in it (NOTE HOW IMPORTANT THIS PART IS). In several months, pedophiles will find your imageboard and post CP on it until the host takes it down. If you want your CP, you must get it before then, because it is against Internet Law for them to refund you in CP.

And that's how tinyboard works.
