If you not done any changes (no new plugins, themes, costum code) after last time when it worked you should check your db through php my admin because it might be broken table. If you want you can write me ignas.rackus@gmail.com and I will take a look. Because I have fixed my site.

Solution was to log in to php my admin and mark table bp_activity and select repair. After it it fixed itself. Hope this will be helpfull for someone.
