Hello Suman,
Could you please take a look at the website and see how I can solve these issues:
What I am looking for:
1. Hide all theme and plugin names.
2. Hide all aspects of wordpress related version numbers.
I tried playing around with the settings, and I noticed that I could either hide the theme or the plugins, not both at the same time. It then tends to break the formating of visual composer on the pages and woocommerce layout on single product pages.
The website is on wpengine, so I have added the redirect rules too.
Will send you website credentials on the next mail, so you can check it out and see what could be the issue.
