**Your software** My Mautic version is: 5.0.1 My PHP version is: PHP 8.1.27 (cli) (built: Dec 21 2023 20:19:54) (NTS) Copyright (c) The PHP Group Zend Engine v4.1.27, Copyright (c) Zend Technologies with Zend OPcache v8.1.27, Copyright (c), by Zend Technologies My Database type and version is: 10.6.12-MariaDB-0ubuntu0.22.04.1 **Your problem** My problem is: After installing mautic 5.0.1 with composer the server returned a “500 Internal Server Error”. ![Captura de tela 2024-01-14 214636](https://us1.discourse-cdn.com/flex020/uploads/mautic/original/2X/d/d90f4f60c8714f5540b25d5b10fd33439228fc4f.jpeg) I followed the documentation here: [Installation — Mautic Documentation 0.1 documentation](https://docs.mautic.org/en/5.x/getting_started/how_to_install_mautic.html#using-the-recommended-project) and run the command `composer create-project mautic/recommended-project:^5 my-dir --no-interaction` no error during the installation process, just two warning: `Package Sensio/framework-extra-bundle is abandoned, you should avoid using it. Use Symfony instead.` `Deprecation Notice: Return type of Mautic\Composer\Plugin\Scaffold\Operations\ScaffoldFileCollection::getIterator() should either be compatible with IteratorAggregate::getIterator(): Traversable, or the #[\ReturnTypeWillChange] attribute should be used to temporarily suppress the notice in /var/www/html/myprojectfolder/vendor/mautic/core-composer-scaffold/Operations/ScaffoldFileCollection.php:118` And npm warning: `npm WARN deprecated @npmcli/move-file@1.1.2: This functionality has been moved to @npmcli/fs` `npm WARN deprecated stable@0.1.8: Modern JS already guarantees Array#sort() is a stable sort, so this library is deprecated. See the compatibility table on MDN: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/sort#browser_compatibility` Despite this warning I received the message: Congratulation, you have installed the Mautic… Than I pointed the server to html/myprojectfolder/docroot as suggested in the documentation by editing the files 000-default.conf, 000-default-le-ssl.conf and default-ssl.conf, the DocumentRoot path When I opened [mymauticdomain.com/installer](http://mymauticdomain.com/installer) in browser the server returned the 500 internal error. I’m new in mautic and I don’t know how to solve this. I installed some times ago mautic 4.10 without composer and I had no problems, but now mautic 5 no longer supports update without composer. Any help is much appreciated. ---

What does the log say under /var/logs? Also check the permissions on the filesystem. ---

I think it’s a file ownership error. Composer will install all files as root, but it needs to be www-data. ---

Hi joeyk and mzagmajster! Thank you for your replies, the problem was permissions, as you suggested! I run this commands and all worked: ```auto chown -R www-data:www-data /var/www/html chmod -R 775 /var/www/html ``` It was so simple 😏 ---
