Do you have a WordPress security issue, maybe you have been hacked? Are you looking for someone to help you? There is one simple question that can tell you immediately if the person actually knows about the security of WordPress and can provide real help or if they are just trying to make a quick buck offering a service they don't really know how to do. The question to ask them is "Will hiding the WordPress version number help to protect my website?". If they tell it will they don't truly know about WordPress security and you need to avoid them. While the claim that hiding the WordPress version number is frequently repeated as something that will protect you, it is very wrong.
