Hello

Is my first time deploy in AWS server the operating system is Linux 4.14.232-177.418.amzn2.x86_64 on x86_64 usin Apache 2.4 PHP 7.3. The _lib to configure the connection is working but the login page send http error 500. All directory have 777 permissions.

Any ideas why I have http error 500 .

Thanks for you help
