Symfony 3 shared hosting error 500



I am trying to deploy my symphony application on a shared hosting but I keep getting error 500.


500



I structured the app, bin, src and vendor on the parent folder then I changed the web folder to public_html on cpanel.


src


cpanel



when I run the URL using example.com/app_dev.php it works fine.


URL


example.com/app_dev.php



However when use example.com i get error 500, so I toggled the PHP option on cpanel to display_error and this is the error I am getting:


500


PHP


cpanel


display_error

Thanks for





Does the file at /home/kaftenh1/var/bootstrap.php.cache exist? Note the .. in the path goes upa level, removing public_html from the path

Thanks everyone. Really appreciate. From your answer and comments i figured the what the problem was. I changed the path in app.php to point where the bootstrap.php.cache is.


<?php

use SymfonyComponentHttpFoundationRequest;

/** @var ComposerAutoloadClassLoader $loader */
$loader = require __DIR__.'/../app/autoload.php';
include_once '/home/kaftenh1/var/bootstrap.php.cache';



If you have ssh access to the server you can then login to the server and open the website project and run


composer install



If you dont have ssh access try to use webconsole .

Firebase Auth - with Email and Password - Check user already registered

Clash Royale CLAN TAG #URR8PPP Firebase Auth - with Email and Password - Check user already registered I want to check when a user attempts to signup with createUserWithEmailAndPassword() in Firebase user Authentication method, this user is already registered with my app. createUserWithEmailAndPassword() 8 Answers 8 To detect whether a user with that email address already exists, you can detect when the call to createUserWithEmailAndPassword () fails with auth/email-already-in-use . I see that @Srinivasan just posted an answer for this. createUserWithEmailAndPassword () auth/email-already-in-use Alternatively, you can detect that an email address is already used by calling fetchSignInMethodsForEmail() (previous called fetchProvidersForEmail() ). fetchSignInMethodsForEmail() fetchProvidersForEmail() When the user trying to create an user with same email address, the task response will be "Response: The email address is already in use by another account." mFirebas

Clash Royale CLAN TAG #URR8PPP Dynamically update html content plain JS So I have a script bound in my index.html, which literally has to fetch an array of jsons from an api, then dynamically update my page when get response. But as a result I'm getting an as the only update of my page. here is my script fetch(url) .then((resp) => resp.json()) .then((resp) => resp.results.forEach(item => fetch(item.url) .then((response)=> response.json()) .then((response) => pokeArr.push(response)) .catch(console.log) ) ).catch(console.log) const filler = () => if(!pokeArr) return 0 pokeArr.map((i,j)=> return `<tr>$i.name</tr>` ) const pokeindex = () => document.getElementById('a').appendChild(document.createElement(filler())) pokeindex() When I'm consoling it, I can see in the console all the responses I get, so I'm at least doing the fetching part right. What's parberakan ? What's pokeArr ? – T.J. Crowder Aug 8 at 12

How to determine optimal route across keyboard

Image
Clash Royale CLAN TAG #URR8PPP How to determine optimal route across keyboard I'm trying to automate the typing process in a video game. Players are given an on-screen QWERTY keyboard layout that they can navigate with the control stick (up, down, left, right) in order to select a letter to type. I was wondering if there was a module for Python (or some other resource I could explore) that would help my program find a path across the keyboard as it types each letter in a given message. In other words, if the first letter typed was "A" and the next letter was "B", the module would know that the program should move 1 space down on the keyboard and 4 spaces to the right. Currently, I have the program resetting to the "G" key after each letter is typed (allowing me to use fixed-directions as the program parses each character in the desired message). As you can imagine, this is quite inefficient and defeats the purpose of automating the typing in the fir
