Ok, the problem is clear:
- Your composer based Drupal site puts your code base to the /web folder
- You are using a shared hosting which maps your primary domain to /public_html, and you can't change that
Now your users will have to browse your site as http://example.com/web . And it is not cool.
So how to serve your site from the subfolder /public_html/web but removing the /web suffix so it becomes transparent to users?
Here are the steps, as I learned from this thread on Drupal.org
1. Open your settings.php file and add the following code:
if ( isset($GLOBALS['request']) && '/web/index.php' === $GLOBALS['request']->server->get('SCRIPT_NAME') ) {
$GLOBALS['request']->server->set('SCRIPT_NAME', '/index.php');
}
2. Create a .htaccess file on the /public_html folder with:
<IfModule mod_rewrite.c>
RewriteEngine on
# Redirect to the subdirectory because that's where Drupal is installed
RewriteRule (.*) web/$1 [L]
</IfModule>
3. Update .htaccess under /public_html/web folder
Uncomment the line RewriteBase and set it to:
RewriteBase /web
4. Clear the cache and run update.php
Your site should work by browsing http://example.com now (without the /web suffix). Your menu items may still have the /web part, but it will be gone after some hard refresh.
5. (Bonus) If you want to redirect http/https and www/non-www:
On the .htaccess file under /public_html/web, please add those lines between the <IfModule mod_rewrite.c> tag:
This is to redirect non-https + www to https + non-www:
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\.example\.com [NC]
RewriteRule (.*) https://example.com/$1 [L,R=301]
And this is to redirect non-https + non-www to https + www"
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^(.*)$ [NC]
RewriteRule (.*) https://www.%1/$1 [R=301,L]
You can see those examples on Htaccess guide.
