 * I’ve purchased a plugin called WPLMS and I’ve just gotten round to finally installing
   it, it’s 160mb and I get a 503 error after a few minutes of trying to add the
   new plugin, nothing will happen. I’ve used a plugin to also set my upload maximum
   to 256mb which is the most my host will allow.
    Any ideas?

 * A 503 error is a server error. You need to look at the error logs on the server
   to find out what the error actually is.
 * The 503 service unavailable error occurs when your web server is unable to get
   a proper response from a PHP script. This PHP script could be a WordPress plugin,
   a theme, or a misbehaving custom code snippet, etc. If these methods fail to 
   resolve the error, then try contacting your hosting provider.
