500 - Internal Server Error (End of script output before headers)

pure guess: your phalcon extension isn't loaded correctly / working

pure guess: your phalcon extension isn't loaded correctly / working

In that case PHP would raise fatal error:

PHP Fatal error: Uncaught Error: Class 'Phalcon\Mvc\Micro' not found in...

So it's some other mis-config.

@OP: provide full app/web server config, OS, PHP version etc.

• OS
• Web server / SAPI used
• PHP version
• phpinfo()

• CENTOS 6.9 kvm
• PHP Version 7.0.22
• CGI/FastCGI
• Apache 2.4
• Phalcon 3.2.2

Do you need any information?

is error reporting on ? maybe some folder permissions ?

Did you try to enable phalcon debugger? More on: https://docs.phalcon.io/en/3.2/debug

Yes, debug enabled.

@afbora: if I remember well, you are developing on Windows (app server)?

Yes i developing windows server (wampserver) but;

1. Built the project on windows server (works)
2. Moved the my linux server (works)
3. Moved the client linux server (failed)

@afbora: if I remember well, you are developing on Windows (app server)?

My server not nginx, i found the errors only apache error.log file like that:

End of script output before headers: index.php, referer: https://domain.com

Server using 2.6.x kernel? OMG, that's 10+ yrs old.

I'm guessing permissions are wrong - i.e. web server user is unable to write into cache directory etc.

OR it might be that you're loading Phalcon before other required extensions such as PDO.

You don't even supply ordering for extension: /opt/cpanel/ea-php70/root/etc/php.d/phalcon.ini

rename it to something like:

/opt/cpanel/ea-php70/root/etc/php.d/90-phalcon.ini

I renamed as 40-phalcon.ini and restart the apache but still getting same error.

I realized that:

Debug the following line on index.php file:

echo $application->handle()->getContent();

I dumped the $application in index.php and printed output.

I dumped the $application->handle() but not output (Internal Server Error).

I install the Invo app but same error (https://github.com/phalcon/invo)

I still see old version on your server: /opt/cpanel/ea-php70/root/etc/php.d/phalcon.ini ?

Temporary enable errors in PHP and see what will be printed on screen.

Also, it might be that you have core dump, check dmesg after you hit your homepage, look for SIGBUS or SEGFAULT errors.

So you have double checked file system permissions and you confirm web server user is able to write to cache dir?

Did you compile Phalcon manually or you have used packagecloud repo?

Installed with cPanel EasyApache 4

@afbora, could you please add this on top of your index file and post here, what you get?

function onShutdown() {
    $error = error_get_last();
    var_dump($error);
    die;
}
register_shutdown_function("onShutdown");

If it's still 500 page, then there is really something dying, what is no regatding Phalcon. Otherwise - you should see the reason in output.

Still getting "Internal Server Error" error, no another output :(

Well, I'm pretty sure there lies your issue. Solutions like XAMPP, WAMP, cPanel etc. will only cause you trouble.

Remedy: compile Phalcon from source.

This is client server but installed the Phalcon with cPanel on my server too but it's working.

Just check logs :)

Here the log:

End of script output before headers: index.php, referer: https://domain.com

Just check logs :)

You need to check other logs, like syslog etc, this is only information from apache/nginx. Check with xdebug/gdb what exactly is happening.

This issue solved.

I installed the phalcon via cPanel EasyApache but not installed correctly.

I installed Phalcon extension via manual method, its working now.

I guess this issue about the server because of i installed the Phalcon to own server via EasyApache and it had worked.

Thanks for helping friends..

Any Solution without installing phalcon from the source? I have the same problem. I also made the installation from easyapache 4, according to the phpinfo () phalcon is correctly installed.
