This question originates from my post on MyBB support forum. It's been a few days so I figured I should ask somewhere else too.I want to prevent the search engines from offering the Cached version of my pages and I want the code to work across the entire MyBB forum which is using 1.8.10. I found this at HTMLGoodies.com: <meta name=robots content=noarchive>It's very very old so do we need to change it at all to use it in 2017? I found this at WillMaster.com:<meta http-equiv=cache-control content=max-age=0>http://www.willmaster.com/library/web-content-prep/preventing-browser-cache.phpand supposedly it will work across all browsers which sounds way better than the first code. Lastly I found this at Tech-FAQ.com:<meta http-equiv=Pragma content=no-cache>http://www.tech-faq.com/prevent-caching.htmlBut they mention it's for web hosts and is a server-side solution. So I don't know if they mean this code is intended for say, HostGator, or if it's for anyone who has access to their site's code.Which of these should I use? Where is the code I have to change located and can you show a screenshot of the code before and after the changes? I found headerinclude in Ungrouped Templates but there is no <head> tag anywhere.Edit: Only the first line of the last two codes was showing up here so I added a link to where you can see the entire code.Edit 2: Giant embarrassing typo in the title. Fixed.
What do I use to tell search engines not to offer a Cached version of my MyBB forum pages and where is the code I need to alter?
