Interval Server Error after installation about addchat-codeigniter

[classiebit]

Hi, make sure you've added this same base_url in application/config/config.php

[GirkovArpa]

$config['base_url'] = 'http://localhost:3000/';

Same error, using the command php -S 127.0.0.1:3000 run via command prompt in the project directory.

Hosting the site with XAMPP instead, I get this error:

addchat.min.js:21 POST http://localhost/addchat_api/get_config 404 (Not Found)

There is a file:

application/controllers/Addchat_api.php

But not a corresponding file in the views folder. This file does not exist:

application/views/Addchat_api.php

Could that be the problem? Shouldn't the addchat installation have created such a file?
