在主机上传项目后禁止访问

I made my website by yii2 in localhost with xampp, that it works without promblem.

But now after upload my website on linux host I got bellow error:

Forbidden

You don't have permission to access /index.php on this server.
Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.

This is my htaccess content:

RewriteEngine on
# If a directory or a file exists, use it directly

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

RewriteRule . index.php 

Why this error occurred ?

If you are using cpanel/WHM, you can change permission through the file manager. If it is still not working for you then delete the index.php and uploaded a new fresh one.

Also, check .htaccess in document root for any error.
