内部服务器错误500，应仅出现“ PHP”错误

Question

my friend ordered a VPS and we're having some issues with it. The server responds with 500 Internal Server Error when there should be a php error telling me what's wrong.

For example I had this script:

<?php

echo 'hi';


?>

for testing and it was just for a test. Then I made some errors into it so that normally php would just throw some errors:

<?php

echo 'hi';
sdsd
sd

?>

But in our case the server now throws a 500 Internal Server error instead showing a small warning. I didn't change any file permission or anything that could cause this, I think it's the configuration.

Here i am posting the php.ini:

Thank you very much

Answer 1

you should inspect your error.log

Also, wiki quotes

500 - generic error message, given when no more specific message is suitable

In my experience i have also encountered such issues with php files having permission of 777. try inspecting your php file's permission. if found 777 turn it into 755.

Once the php files have 777 permission, it is stopped and throws an error 500.
