I am trying to activate and use W3 Total Cache on my blog. At first, I thought I wasn't installing it correctly, because it wasn't showing up in my list of plugins that I have installed. Then I realized that when I try to install it, it says that it has already been installed. W3 Total Cache is also showing up as an installed plug-in in my FTP client, so I know I installed it correctly. I just don't know why it's not in my list of plugins on WordPress. Has anyone else had a similar problem?
