[Plugin: Buddypress, BBpress] site title

Hello ?? I use Buddyboss 3.2.3 with Buddypress 2.0.2 and BBpress 2.5.4. I have problem with site title. In the source code I have the following (i.e.):

<title> Group’s name | Forum title | Topic title | </title>

I would like to have:

<title> Topic title | Forum title | Group’s title | </title>

Is it any way to do it? I’m the beginner in wordpress and I don’t know, where I can find this.
