As the title says, I have a VPS running on CentOS 7, I installed all the requisites for Laravel, PHP 7.3, but it still giving me 'Server Error 500'.
Note that this is a fresh installation of Laravel with composer.
- My CentOS version is CentOS Linux release 7.2.1511 (Core)
- PHP version is PHP 7.3.6 (cli)
- I manually installed all the necessary modules from PHP
What I have already tried
I already did quite a lot of research:
Laravel giving 500 internal error on centos 7 with apache and php 7 
I followed what the answer to that questions says and still the same for me.
I did also set up permissions correctly following this other post:
How to set up File Permissions for Laravel 5 (and others) 
Also these ones 
Getting a 500 Internal Server Error on Laravel 5+ Ubuntu 14.04
https://www.ionos.com/community/server-cloud-infrastructure/apache/how-to-fix-http-error-code-500-internal-server-error/
And a bunch of more articles I read on another websites.
These are the permissions for the project folder:
drwxr-xr-x 13 apache apache 4096 May 31 05:23 laravel
And for storage:
drwxr-xr-x  5 apache apache   4096 May 31 04:44 storage
Tried generating the key and got this:
[root@server laravel]# php artisan key:generate
