I want to hidden my content management source until w3techs.com/sites can't to find my content management info.
I want do it because my Customers don't think well about WordPress and don't want visitors to understand the site engine.
What do you mean "hide it"? There is no reason that anyone has to know what you've built your website with. Do you mean if they look at the source code for the page? Try this, it may have what you are looking for: http://wordpress.org/extend/plugins/secure-wordpress/ As for what your customers think about Wordpress, I could go on for day about how warped that is. 22% of EVERY website online uses Wordpress, and growing, as well as 14% of the top 1 million sites, and over 50% of the Top 500 Companies in the world. It is the most used web publishing platform on the entire World Wide Web. I'm sure your customers are on Wordpress driven sites every day and have no idea. If what you say is a true representation of how they feel, then you have a very uninformed customer base. Either that or they just like to complain about things. What software someone uses is of no importance to the user, unless the site is poorly designed.
OH, I see. It's some script that you are talking about. Did you check the plug in I linked to? If that won't suit your needs, then try disabling right click functions: http://www.hypergurl.com/norightclick.html Do you really think you users have nothing better to do than check your website with some script to see if you are using Wordpress, so that they can judge you? I think, the fact that you are hiding it, will make them think you are using it anyway. Seems like a really silly, trivial thing to me, but it's your site. If it's important to you, then it's important.
