title: mpm_winnt:notice and core:notice in Apache log. Is it ok?
body: <p>Well, my problem is that I have <code>500 Internal Server Error</code>, but I'm unable to figure out what it is. I switched to php.ini-development as php.ini, I turned on all error reporting I could, I created and set <code>error_log</code> file in php folder. But nothing is reported. My simplest in the world php file looks like this:</p>
  
  <pre><code>&lt;?php
    ini_set('display_startup_errors',1); 
    ini_set('display_errors',1);
    error_reporting(-1);
    echo "Hello";
  ?&gt;
  </code></pre>
  
  <p>However, no errors are displayed. What really drives me nuts, is that the page itself is executed, so that I see <code>Hello</code> in my browser, but still in the console I see this notorious <code>500 Internal Server Error</code>. </p>
  
  <p>PS. Apache error log contains nothing more than this:</p>
