Every links on my wordpress site keep showing the site activity from buddypress!

Please help me…im in abig trouble..
this is my client website that i working on right now, and this problem started when i installed the sharethis plugin.

When i installed this plugin, whats i am getting is that all the links at the navigation bar, and also any links that i put on as the url for this website, will keep showing me the same content which is the “site activity” from the buddypress.

I’ve tried to uninstalled this plugin, but the website keep doing the same thing.
