i using basic yii2 template. there no htaccess file , config file reads:

<?php  $params = require(__dir__ . '/params.php');  $config = [     'id' => 'basic',     'basepath' => dirname(__dir__),     'bootstrap' => ['log'],     'components' => [         'request' => [             // !!! insert secret key in following (if empty) - required cookie validation             'cookievalidationkey' => 'gfwix3xdsocyeuve6vvm1kf4vayt0z7t',         ],         'cache' => [             'class' => 'yii\caching\filecache',         ],         'user' => [             'identityclass' => 'app\models\user',             'enableautologin' => true,         ],         'errorhandler' => [             'erroraction' => 'site/error',         ],         'mailer' => [             'class' => 'yii\swiftmailer\mailer',             // send mails file default. have set             // 'usefiletransport' false , configure transport             // mailer send real emails.             'usefiletransport' => true,         ],         'log' => [             'tracelevel' => yii_debug ? 3 : 0,             'targets' => [                 [                     'class' => 'yii\log\filetarget',                     'levels' => ['error', 'warning'],                 ],             ],         ],         'db' => require(__dir__ . '/db.php'),     ],     'params' => $params, ];  if (yii_env_dev) {     // configuration adjustments 'dev' environment     $config['bootstrap'][] = 'debug';     $config['modules']['debug'] = [         'class' => 'yii\debug\module',     ];      $config['bootstrap'][] = 'gii';     $config['modules']['gii'] = [         'class' => 'yii\gii\module',     ]; }  return $config; 

if app called basic, url should work:

https://portfolio-php.herokuapp.com/basic/web

how basic app working in domain/

1) move files /web directory public_html or whatever

2) put rest of files in upper level, that:

[...] commands config controllers models web (empty) ... public_html  - assets  - index.php  - css  - [...] 

3) change index.php you've moved /public_html , change paths config files, vendor, etc.

4) create .htaccess in directory following:

options +followsymlinks -indexes indexignore */*  rewriteengine on  # if directory or file exists, use directly rewritecond %{request_filename} !-f rewritecond %{request_filename} !-d  # otherwise forward index.php 

====

update

check if https://portfolio-php.herokuapp.com/basic/requirements.php works, if not, should reinstall composer dependencies:

• backup vendor folder , composer.lock

• delete files in vendor folder

• do composer install --prefer-dist
