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.

That's it. That's the last straw. /prog/, I just want to let you know that I've grown out of this board. This underlying dark philosophy of "I don't give a fuck," "Dark thoughts are humorous," and "Anarchy>Order" epitomizes the mental flatulence of the population of immature and unappreciative people. It hasn't gotten anyone anywhere throughout history, and it has only brought me down in the past. Trolling to hurt people intentionally isn't funny, and if you think it makes you funny, intelligent, or generally superior you are a master at lying to yourselves. One of the important parts of being a man encompasses taking care of the less fortunate, and this includes the intellectually less fortunate. Atheists: Stick to something less extreme like "I hypothesize that God doesn't exist." Going around saying "I know God doesn't exist" is also a lie. He doesn't exist in your own subjective reality, and that's all you know. Do yourselves a favor and look up existentialism or secular humanism if agnosticism has a bad connotation. I'm rambling though. /prog/, as much as you think you have life all figured out, you're just a bunch of people with generally an above-average intelligence who are too smart to say "I don't know" sometimes but too stupid not to. If I've grown out of /prog/, why did I say all this? Everyone deserves advice even if most of you are going to turn it down, but if you're turning it down immediately then I hope you're hurt by it because if you're a dick for life then you deserve to be hurt like you hurt others. You immature little beta shit. I'm going to Reddit.
