I'm trying to configure W3TC fragment caching with Visitor's Map Who's Online plugin. I read the W3TC FAQ about using the mfunc tags for fragment caching, but I'm a bit of a novice when it comes to wordpress and php. I'm not exactly sure what templates, where in them or which pieces of php code I would need to add the tags around. Trying my best to learn. Thanks in advance for any help you can provide!
