Urgent: Help needed — Document root locked, 504 Gateway, PHP settings & app setup (username: osamalovirboy, site: turkiii.helioho.st)

[osamalovirboy]

Hello HelioHost Support Team,

My account username: osamalovirboy
Affected site / subscription: turkiii.helioho.st

I uploaded a PHP/Laravel application to my hosting via Plesk File Manager, extracted the files into httpdocs, and now I get a "504 Gateway Time-out" in the browser. I am a beginner and need your help to make the site run correctly. The Plesk control shows the Document Root field locked (value: httpdocs) and I cannot change it.

Please assist with the following items (step-by-step or perform them on my behalf if possible):

1) Document Root
   - Please change the Document Root for this subscription to: 
     `httpdocs/public`
   - If you cannot change it, please advise and perform the secure alternative: move the **contents** of `public` into `httpdocs` and update index.php autoload paths correctly (or tell me you will do that).

2) PHP version and extensions
   - Confirm the PHP version assigned to my site (I saw PHP 8.3.21 in Plesk — please confirm).
   - Ensure the following PHP extensions are enabled for this domain:
     `pdo_mysql, pdo, mbstring, fileinfo, openssl, tokenizer, xml, ctype, json, bcmath, gd`.
   - If any extension is missing, please enable it or tell me the steps.

3) File permissions (storage & cache)
   - Set the following permissions (recursively) on the app directories:
     - `storage/` → 775 (owner write)
     - `bootstrap/cache/` → 775
   - Confirm these were applied.

4) Database & .env
   - Confirm the MySQL database was created successfully and that I can access phpMyAdmin.
   - If you prefer, I can create the DB and user; otherwise please confirm the DB name and username assigned.
   - Confirm that `.env` file is in place and that `APP_URL` is set to `https://turkiii.helioho.st`.

5) APP_KEY and Composer
   - Please run (or allow me to run) the following commands from the project root:
     - `composer install` (if vendor is missing)
     - `php artisan key:generate`
     - `php artisan config:cache`
     - `php artisan route:cache`
     - `php artisan view:clear`
   - If you need the exact PHP binary path for Plesk, please use `/usr/bin/php` or the appropriate PHP CLI path on the server.

6) Scheduled tasks / Cron
   - Enable cron / Scheduled Task that can call a URL or run curl/wget. Example cron command for scheduled posting:
     ```
     * * * * * /usr/bin/curl -s "https://turkiii.helioho.st/post/cron" > /dev/null 2>&1
     ```
   - Please confirm whether `curl` or `wget` is available for scheduled tasks.

7) Logs and cause of 504
   - Please check the latest webserver / PHP / application error logs for `turkiii.helioho.st` and paste the last 20 lines of relevant errors (or tell me what you found). The 504 appears immediately after I uploaded the app — I suspect the document root or missing app setup is the cause.

8) Security / .env protection
   - Ensure `.env` is not accessible via the web (deny public access to `.env`) and confirm `.htaccess` rules or server-level rules applied to protect sensitive files.

9) If you perform the changes
   - If your team can perform the above changes, please reply with:
     - Which steps you performed
     - The exact Document Root path set
     - DB name and DB user (so I can update `.env` if necessary)
     - Confirmation that APP_KEY was generated
     - Confirmation that cron is available and working
     - Any remaining manual steps I must run via Plesk File Manager

I am new to this, so please provide brief step-by-step feedback or do the fixes for me if possible. Thank you very much for your assistance — I can provide any screenshots or additional details you need.
