PHP errors creating, viewing groups

hello, thank for your quick reply :).

I'm upgrading from Commons 1.4

Here seems to be the error:

I finally succeed in reborn my groups by activating one or two module but I'v no more last content (activity message) published on the home page of each group. i think I have another action to do for this but I'm a little bit lost. Is it the activity stream that I have to set up for all groups?

ok I reply to myself.

I just had to regenerate the Activity log. it's work for now.

Last error I have is when I create a group. The group is created but with this error first:
Fatal error: Call to undefined function og_subgroups_include() in D:\apachewww\actit_v2\profiles\drupal_commons\modules\contrib\og_subgroups\modules\og_subgroups_prop\og_subgroups_prop.module on line 85

Thanks
