title: Apache won't start in MAMP on PC
body: <p>I'm using MAMP on Win 8.1. It has been working fine. But today I opened it up and it threw an error "Could not wait for starting of Apache child." It was MAMP 3.0.1. I then tried uninstall and re-install it as is mentioned in
  <a href="https://stackoverflow.com/questions/27232761/mamp-error-couldnt-be-started">MAMP error: couldn&#39;t be started</a> . The new version is MAMP 3.0.4. But instead of throwing errors, it simply stuck at the starting window with the green bar scrolling forever...</p>
  
  <p>Other posts I could find about this problem are mostly MAC versions, and I can't find any file named "envvars".</p>
  
  <p>However, on both MAMP 3.0.1 and 3.0.4, if I switch the version of PHP in "Preferences->PHP->Standard Version" to anything other than 5.6.7, it worked. Is it that the windows version of MAMP still doesn't support PHP 5.6.7? But it worked fine before today...</p>
