title: Apache won't run in xampp
body: <p>I have just installed XAMPP and everything works fine except that I can't get apache to run.  It seems that port 80 is the problem, I have disabled Skype to use port 80 but it doesn't seem to fix it.  I read somewhere that the SSL port can be the problem and should be changed.  But I cant figure out were the port is or how to change it.</p>
  
  <pre><code>"Check the "/xampp/apache/logs/error.log" file"
  </code></pre>
  
  <p>I have tried to check this file but inside "logs" there isn't anything. From apache I can go to error but there is not any recently changed documents. </p>
  
  <p>The error:</p>
  
  <pre><code>20:34:24  [Apache]  Problem detected!
  20:34:24  [Apache]  Port 80 in use by "system"!
  20:34:24  [Apache]  Apache WILL NOT start without the configured ports free!
  20:34:24  [Apache]  You need to uninstall/disable/reconfigure the blocking application
  20:34:24  [Apache]  or reconfigure Apache to listen on a different port

  20:40:51  [Apache]  This may be due to a blocked port, missing dependencies,

  </code></pre>
  
  <p>How to I fix these errors?</p>
