My Caddy File

http://bot.vibs.tech {
root /home/caddy/www/botsite
tls off
errors {
    404 /home/caddy/www/botsite/404.html
}
fastcgi / 127.0.0.1:9001 php {
ext     .php
split   .php
index   index.php
}

}

The Webpage http://bot.vibs.tech/test.php
Home Page http://bot.vibs.tech

My PHP Script

<?php

if($_POST["submit"]) {
    $test=$_POST["botsname"];
    $redis->set(';message';, $test;);
    $value = $redis->get('message');
    <p>$value</p>
}
if (empty($url)) {
    echo "<h2><div style=/"color: Black;/">THANK YOU, YOUR BOT IS BEING MADE!</div></h2>";
    echo "<h2><div style=/color: Black;/"><a href=http://bot.vibs.tech/>HOME</a></div></h2>";
}

Tried lots of different things, not sure what else i could try to do.

Also im trying to implement Redis to this so i can have a database from a form im currently working on.
