Hello, Some users are experiencing ERROR 500 on my website https://creek.is while my computers are not showing this error. What could be the problem ?
Thanks for replay. Here is an php5 error but I'm using php7 Code: 2017/08/08 **:**:** [error] 2273#0: *48468 FastCGI sent in stderr: "PHP message: PHP Warning: session_start() expects parameter 1 to be array, string given in /var/www/clients/client5/web30/web/wp-includes/class-wp-hook.php on line 298" while reading response header from upstream, client: **.***.***.**, server: creek.is, request: "GET / HTTP/1.1", upstream: "fastcgi://unix:/var/lib/php5-fpm/web30.sock:", host: "creek.is"
The error message does not indicate if the site uses PHP 5 or PHP 7, the socket path is the same for all PHP versions. If you want to know the php version, add a phpinfo() file in the website. And regarding this error, you pass a wrong variable type to the session_start() function.
Thanks for replay.

That's a problem with the PHP code. As you can see, PHP 7.1 is used. There is a lot of software that is not compatible with PHP 7.1, so I would recommend switching the site to PHP 7.0 or PHP 5.6 if you have multiple PHP versions installed to see if it works then.
