Evaluate if your topic is in scope of support of our board. We don't want to provide...

[...]

• ...support for live, production or public accessible environments.
  XAMPP is not configurated for such environments (default passwords, many activated and probably unnecessary modules, not tweaked for performance, scalability, stability or security). This board does have several entrys about hacked XAMPP installations because of using unprotected XAMPP installations in not supported environments. XAMPP don't want to fit every possible use case and there are other (also free) alternatives for such environments.
  
• ...enterprise or commercial oriented support.
  You and/or your company earns money for what you are doing. If you don't have the knowledge to solve XAMPP problems on your own, spend a part of your money to hire an expert or pay an it freelancer to solve such problems. We all need jobs and money to live and in a company or commercial oriented environments there are much more things to consider like legal requirements or network security. Every action can contain a financial risk so even answeres on simple questions have to be analysed if they fit all the rules the environment requires. This cannot be achieved in two sentences of a forum post.
