You just installed a JoomlaStats extension (for example module mod_jstat_flags) but it does not work. On the front site you see the message "It seams that you did not install..."
When you find your way to this page, you probably tried to install one of JoomlaStats extensions (like module mod_jstat_flags) without installing the JoomlaStats engine (com_joomlastats).
Probably on your page you have the message: "It seams that module Flags (mod_jstat_flags) is not installed correctly. Please refer to JoomlaStats Extension installation problem page."
Mainly there could be 2 reasons for this:
1) You do not have installed JoomlaStats engine (com_joomlastats) -> please install it. Have a look at SSS: 3 Simple Steps to Setup for help on how to do this.
2) This particular extension needs a more recent version of the component -> please check it on JoomlaStats Extensions page and/or install newer engine (see point 1).
