 * After installing, deleting or updating plugins, why do I get a message at the
   top of my admin WordPress page with the following message?
 * `<blockquote>One or more plugins have been activated or deactivated, please empty
   the page cache and check the minify settings to maintain the desired user experience.
   Hide this Message.</blockquote>`
 * Which option is preferable to select? Why?
    What actually happens with I empty
   the page cache? Can the search engines still find my [site](http://www.Cannabis-Seeds-Canada.ca)?
 * Looking forward to the clarification shortly.

 * Hi Susanne,
 * When you install, delete or update a plugin, it (generally) changes how your 
   site looks, how it works, etc.
 * W3TC is letting you know that if you desire to see reflected on your website 
   the changes the installation, deletion or update of a plugin has caused, you 
   must purge the cache so that a new cache, with the changes made, can be generated.
 * Otherwise, the changes will not be reflected until (or if) a new set of cached
   pages are generated automatically. Automatic cache generation may happen at different
   times for different pages; so, purging them all at once assists with maintaining
   the user experience you hope to achieve with your plugins.
 * After installing, deleting or updating plugins, you want to check the minify 
   settings since, as just one example, and if minifying manually, a new plugin’s
   JavaScript files will not automatically combine themselves into an existing, 
   manually created combined file.
 * Best,
    AJ
